Original 1st printing 12 x 21&1/2" 1st version/1st state (preliminary lineup) concert/event poster for the (second) Miami Pop Festival, held at Gulfstream Park in Hallandale, FL from 12/28-30/1968.

 Acts listed on the poster include: Jose Feliciano, Buffy Sainte-Marie, Country Joe & the Fish, John Mayall's Bluesbreakers*, Chuck Berry, the Infinite McCoys, Booker T. & the M.G.'s, Fleetwood Mac, Dino Valente* and Blues Image (12/28), Steppenwolf, Jr. Walker and the All-Stars, Marvin Gaye, Joni Mitchell, Flatt & Scruggs, the Butterfield Blues Band, the James Cotton Blues Band, Richie Havens, H.P. Lovecraft* and the Box Tops (featuring Alex Chilton) (12/29), Jose Feliciano, Grateful Dead, Iron Butterfly, the Turtles, Canned Heat, Grass Roots, Ian & Sylvia, the Charles Lloyd Quartet, Sweet Inspirations and the Joe Tex Revue (12/30). (*canceled) Not mentioned/added later: Procol Harum, Three Dog Night, Pacific Gas & Electric, Hugh Masekela and Sweetwater)

 Design by Procity, thick foil-coated cardboard stock poster is in excellent (B+) condition; there is a prominent 3&1/2" hard horizontal bend in the lower right corner (going through "$6.00"), a thin 3/4" vertical bend in the lower right margin/corner, a set of tack holes (all four corners, a few tiny edge dings, a series of ULTRA-light surface scuffs and tiny scratches hiding within the image area and a couple of tiny corner bumps/pressure creases, otherwise fine. 

 MEGA-SCARCE (and REALLY cool-looking) hard-to-find South Florida festival item with a great pop art/psychedelic design and a VERY eclectic lineup of rock, folk, jazz, R&B, bluegrass and pop. While the red lettering/final state version turns up from time to time, this is the ONLY example I have ever seen that was printed on cardboard. INCREDIBLY cool (and possibly unique) 1968 Festival poster! You can stream the Grateful Dead's set (arguably one of their best shows of 1968) HERE;
