If there is a work that catches your eye, there are a few ways that you can evaluate the artwork and creator:
Research the creator's background to learn more about their practice
Review the creator's Twitter or Instagram accounts to get a sense of their online presence
Check to see who invited the creator to join Foundation and review their profile
Ultimately, if the story behind the artwork or the creator resonates personally with you and you are confident that you want to own the piece, take the leap and place a bid.
