The Grateful Dead Concert Poster Avalon Ballroom San Francisco 20.5 x 14.25

The Grateful Dead Concert Poster Avalon Ballroom San Francisco 20.5" x 14.25". This is in really good used condition with light signs of wear. Pins were used to hold it up from the corners previously. I've taken a lot of close up pictures but I'm not an expert in historical posters so I'm unsure if this is an original 2nd print.

It looks similar to others but please take a close look to determine. I'm more than happy to provide additional pictures for reference if desired. Feel free to reach out with any questions or requests for additional images. I'm more than happy to help! Check out my other listings!
