He may be gone, but he is certainly not forgotten - and one Glasgow gallery is making sure of that.

The Glasgow Print Studio have today launched a new post-houmous collection of Alasdair Gray's prints and lithographs, 'Omnium Gatherum', many of which featured in the covers of his original works.

Featuring over 38 original prints, the collection includes pieces from 1981 until 2019, just before Alasdair's death in December of last year.

For many it will be the first time they can view the original lithographs that adorn the covers of Lanark, which were made by Alasdair in 1981; or, his series The Scots Hippo, inspired by T S Eliot and translated into Scots language after issues with the Eliot estate.

Claire Forsyth, Workshop Manager of the Glasgow Print Studio, worked closely with Alasdair for over a decade on his prints. Her name is even included in 'Lanark (Book Jacket), recreated in 2014 and dedicated to Alasdair's wife, Morag, and son, Andrew. Claire spoke of the unique relationship the two had formed over those years.

"Alasdair was incredibly generous, with his time and with talking to people" Claire told The Glasgow Times.

"Art students would show up on his doorstep without letting him know. He would give work away and his studio that he worked in was so interesting - crammed full of paintings.

"Everything was living; a lot of the paintings and the prints were not in a final state. He would go back to a 30 year old painting and work on it again - they were all alive to him. I think especially after his accident, he had his work hung in his bedroom. His spent a lot of time looking at it, and after that he would want to remake and rework on them.

Alongside working with Alasdair and showing him the new advances in digital technology, Claire was often the student herself.

"Working with Alasdair makes you feel lazy because we are working with people who hae a fire within them, not only making huge bodies of artwork but novels, plays and developing new techniques. We had to put a time limit on Alasdair's work, to three days, to limit the amount of changes and revisions he would make.

Claire used to take prints that were in process of being created by Alasdair to his house, where he would use "mountains of tipex" to paint and repaint sections of the paintings.

"He wasn't even contained by the edges of the paper" she laughed. "He would use sticky address labels to extend the scope of the paper - to literally expand the canvas. It was lo-fi in a way, but encouraging for younger artists. He was one of the greatest artists in our time, but he worked using the most simple of things. At the same time, he was also fascinated by digital technology.

"There was a lot of trust and friendship that was built over the years. As people who know him know, he was a genius, but also a normal human being; he was kind and funny, also prickly and challenging. It's important for people to know that, I think."

Director of Glasgow Print Studio, John Mackechnie, is also immortalised in Omnium Gatherum.

"It's a fabulous exhibition" he said. We've had a long association with Alasdair that goes back to the 70s, we were involved with the publication of his first book, "The Comedy of the White Dog'.

"Shortly after that, he'd obviously been writing Lanark for a long time and he made the illustrations into lithographs. We did bits and pieces here and there over the years and it took off again in 2005, with the Scots Hippo series.

"It was a great experience. When he was drawing, he was in the table next to my desk. To actually have him drawing and guffawing, breaking into song, it was real pleasure. It's a lot of work to do these, a huge investment of time and money.

"We got to a stage to try out colour digitally and he would work with the experts on his work.

"It's a bittersweet experience, having his work here but not having him here to enjoy it. I think its just good to be able to show the work that he has made with us over 40 years, to show the quality and the quantity.

"People who don't know his work will get a better understanding of it, and what is on show here."

Omnium Gatherum will be available to view until April, and many of the pieces can be bought. It celebrates his incredible ethic along with his talent.

"Alasdair was driven" added John. "We had four more years of work from him than we'd have thought. After his fall, no one thought he would return to work, and he even would tell people when he was brought out of his coma that he wanted to die.

"Fortunately, somehow or other, he got through that. The last communication I had with him he told me he had a new image to be included in the show, but I never saw it."

One thing that is proven by Omnium Gatherum is the ubiquity of the artist himself: Alasdair may not be here, but he's not really gone.
