Hmmm... judging from this Wiki page (<a href="https://wiki.roll20.net/Art_Library#Searching_For_Art_Assets" rel="nofollow">https://wiki.roll20.net/Art_Library#Searching_For_Art_Assets</a>) it looks like only the Pro level provides art assets. The wiki refers to them as "Pro Sets" and not "Subscription Sets." If it is only for Pro users, naming it Pro Sets in the interface would be better, IMO. Just to confirm, you should email <a href="mailto:Team@Roll20.net" rel="nofollow">Team@Roll20.net</a> and ask for clarification. I thought Plus users got some art assets, too. And don't forget you have a ton of resources under Free Assets, including some new additions from Paizo.
