Additional notes since people are graciously providing replies and suggestions! :) This is unoffensive, professional level paintings of nostalgic things like typewriters, telephones, gas cans, shaving brushes, etc. None of it should be at risk of any kind of censorship or legal challenges. The artist is a retired guy (my father), so high effort marketing is not an option. The main need is just to have a good place to show off everything he's painted. It's basically a question of what platform or service is ideal for presenting a personal gallery, and optionally with payment processing. Thus far Etsy and Wordpress with plugins have been suggested. My own experience with Shopify makes me think that is an option, although less tailored to the purpose.
