Denver's Clyfford Still Museum holds 95 percent of Still's work -- an Abstract Expressionist who's considered one of the most important painters of the 20th century. This 12-month membership, which allows you free admission every day for a year, is your ticket to understanding the legacy of Still, an artist whose life has been shrouded in mystery and whose work has been hidden for more than 30 years. What's more, as a museum member you'll get access to private events, a discount at the museum shop, a subscription to the members magazine Words on Paper, and other exciting benefits.
