Original 1st printing 9&5/8 x 19&1/4" concert poster for the Lovin' Spoonful (featuring John Sebastian) appearing with the Blues Image (Thee Image house band), the Bangles and the Kollections at Thee Image in Miami, FL on 3/23/1968 (this was second "official" show held at the venue, the week after the Mothers of Invention)
Designer unknown/not credited, medium flat vellum stock poster is in excellent to near mint (B+ to B+/A-) condition; aside from a trio of tack holes (top left/right corners and top center margin), a tiny bend in the bottom left corner tip, a slight soft bend in the lower right margin and a stray soft pinch ding or two hiding within the image area, it is an absolutely UNBEATABLE example of this EXTREMELY SCARCE (and REALLY cool-looking) early-'68 concert poster from Marshall Brevetz' legendary bowling alley-turned psychedelic nightspot in Miami. FANTASTIC design/colors on this piece.
