The Grateful Dead Spring Tour 1977 Poster Itinerary 36" x 24" Rare

Description

One of a kind poster that was in a collection for years in a closet. After doing a lot of research and contacting a few experts, none have a clue about it. It might have been in a record store to promote their tour or at the concert to show their dates.It measures 36" x 24" and is made of paper. Inside the skull are the songs that they did.Poster will be gently rolled and mailed in a shipping tube.
Someone informed me that this poster has the song list as they performed it in order for that year so this poster was printed after the Spring.
