Lesson learned: Hold on to exhibition posters — you never know what they’ll be worth 50 years down the line. Proof of this is a Warhol-Basquiat boxing poster from 1985 on sale for more than $5k. Or a 1953 Henri Matisse poster currently available for an undisclosed amount. We all know what that really means. Prices aside, vintage art gallery posters — such as the above — are a fun and unique way to collect fine art. Scatter the prints among family photos and artwork or let them stand on their own. No matter which way you frame it, a vintage poster is a perfect way to incorporate a piece of history into your home.
