I sell prints at comic cons - but not on my website. Everyone seems to do it and I'm not sure that the publishers/owners would do anything about it - simply because we all sell in such miniscule numbers. If, however, I ran off a run of 2000 Spider Man prints and sold them from my site - I'd possibly expect a bit of attention from the men in suits. ps. I hardly ever use DA. A few PJ people have had work ripped off via this site - and it kinda worries me. So....when I DO post - it's only ever low-res stuff.
Yeah, I should probably start selling prints of my stuff. You're not the first person asking about it. Not sure about the legal aspect though. Any experience there? You seem to do a lot of known characters.
