Original 1st printing Round/Grateful Dead Records promo ("All New Stuff!") 29 x 23&1/8" uncut printer's test proof sheet (poster + six (6) handbills/cards) for the Grateful Dead's 1973 album, "Wake of the Flood".

 Art by (and SIGNED in pencil by) Rick Griffin, medium glossy-coated index stock poster is in decent (B/B-) condition; the main issue with this example is the amount of age spotting that covers the poster- it's fairly subtle in certain areas, while it appears more prominently in others (particularly on the reverse side); the spots are all pretty light and range in size from pin-prick to about 1/4", but they are definitely there- possibly the result of improper storage or a wet/damp environment... beyond that, there are a few light handling/edge dings here and there and a touch of toning to the paper, but physically it is in pretty nice shape- no tears/holes/bends, etc. 

Conditional issues aside, it is still quite presentable overall and it has a nicely-placed Griffin signature.
