I know offsets get dissed a lot because they don't have the "gravitas" of the screenprints,
but there are so many great images out there, and you can collect on the cheap. I have
no problem with someone collecting posters on a budget.
Heck, the New Fillmore series is up over a thousand now. Moonalice is catching up fast.
Plus it's a payday for a lot of artists who also do screenprints. For a working artist, you've
gotta pay the bills. Commissions for offsets and a big part of their bread & butter.
