Maybe, but I zoomed in and took a close look before I posted.
Digital paper texture is just “noise” so tends to look a certain kind of way and I don’t see evidence of that here.
The other thing is how the ink bleeds into the paper. When I zoom in, it looks to me like real ink bleeding into fibers.
All that said, I could still be wrong, it’s actually really hard to tell (the crayon looks sus). But I still think it’s real paper.
Unfortunately we’ll probably never actually know :(
I love that painting!
