Hey, could I use this in a board game I am making? I may eventually pitch the idea to Wizards of the Coast and would like using art with people's permission. I may end up asking this on many of your photos.
Most of the pieces you have inquired about are copyright Fantasy Flight Games and I would therefore direct you to contact them and their legal staff about it; one was commissioned by a smaller RPG company. The safest legal route is to commission new work, and if you're interested in that, please do get in touch.
I would love that, however I have no money for paying for commissioned work at the moment. So if it would cost money I may have to consider making a kickstarter. Thanks for the info and reply, take it easy!
