We have one special print from Kilian Eng releasing in about two weeks that is 24 x 36 inch / 90 x 60 cm but it is game related though. Not as big as
At the Edge of a Jungle of course bur larger than his usual output. I'll ask him if we would consider doing another really large one. He made At the Edge of a Jungle specifically for an art fair in Germany.
We are actually actively looking for digital artists that work in large formats but it is a challenge.
The difficulty with digitally made art is that large pieces/prints are very technically demanding to make still. C&B ideally prints between 300dpi and 600dpi for instance and with images that are > 10.000 pixels wide or high you're looking at file sizes of 4 or 5 Gigs easily. That's hard on Photoshop to get a smooth work flow.
