I love the portraits collections here like for example https://opengameart.org/content/30-painted-portraits

I found https://commons.wikimedia.org/wiki/Category:The_Pilgrim%27s_Progress_(1890) which has some awesome portraits but I'm no good with image-correcting these (borders are not straigth, maybe removing them is better).

Perhaps somebody else will be inspired to do it?

By the way, you totally need a discord! :D
