Logo used in the Mid-'60's... In fact, I'm pretty sure this was one of the very 1st Grateful Dead logos that was every designed? Either right after, or right before I think after?
The 1966 Mouse / Kelley " Bertha " - which 1st appeared on the 1966 Avalon Ballroom Poster... I do know that this design was used on a couple / few GDP " Mailorder " Tickets... The fancy ones - with the glitter. But, no' Glamour' here at all... Just down & dirty'67 Grateful Dead!!- from the Pigpen Era!! And apparently, as the story goes - this Envelope was retrieved from the Grateful Dead 710 Haight / Ashbury House that the Band occupied as a group in 1965 - 1966 through Late-1967.
When they were moving out - some things were left behind... However, I have no Certificate of Authenticity C. Of any sort to provide.
However, it does make pretty good sense - when you think of the actual timeline... On this one - it's just a Complete-Beauty!! And could definitely be framed, collected, or maybe used too to keep Your! Prized Grateful Dead Tickets inside. A bit of wear on both sides, with a few marks - but all things considered... No creases, folds - or anything like that - as this item has been safely collected & stored for well-over 55-Years! My thoughts are that someone out there will treasure this Vintage-Original piece of Rock n' Roll!!- as he looks like nothing will get in his way - for some Good Ol' Grateful Dead Music!!!!! Item Condition : This is an Ultra-Rare! Vintage-Original (Genuine / Authentic) Grateful Dead 1967 G. It is in Very Good condition overall, with a few assorted marks on both sides of the envelope, as shown in the photos provided.
Please see all photos & close-up photos provided for the actual condition of this 55+ year old vintage item.
