You can even make sure that you love the art you choose before buying it — HANG ART rents their paintings and sculpture. They will then apply 50% of the rental fees paid toward the purchase price.
HANG ART also hosts opening receptions for shows in their galleries, as well as collecting talks, artist panel discussions, and other public events. They continually update the inventory and the availability of each work on their website, and frequently bring in new guest artists.
