"All The Years Combine: Deadhead Treasures From The Grateful Dead Archive"

There's a lot of mind blowing stuff in the Field Museum, but none so heady as this special exhibition of Grateful Dead memorabilia. Deadheads and casual fans will be able to enjoy a collection of fan correspondence, decorated ticket request envelopes, newsletters, drawings, posters, tickets, backstage passes, fan-made concert tapes and more vintage pieces from throughout the band's storied history.
