I would like to etch some glassware (beer mugs, shot glasses, etc.) with the Pathfinder Society's "Sign of the Open Road" (and possibly some other Golarion-related symbols) and donate them to a local convention (SkålCon 2016) that would then auction or raffle them off for a local charity (Tubman).
There's no commercial intent in this, but money would be changing hands (the selling of raffle tickets or the winning bid in an auction). And the nature of glass etching would necessitate the alteration of the referenced artwork.
Would this be something I could or could not do?
