Original 1st printing 11 x 17" cardboard benefit concert poster for the Byrds (with Gram Parsons) appearing with Sonny & Cher, Mahalia Jackson, Roosevelt (Rosey) Grier and many more in a benefit for the Presidential campaign of Senator Robert F. Kennedy ("SRO for R.F.K."), held at the Los Angeles (CA) Sports Arena on 5/24/1968. 

 Design by Mortimer, thin cardboard stock poster is in absolutely STUNNING mint/near mint (A/A-) condition; an overall GORGEOUS example of this oddball psychedelic-era benefit poster with a superb design (great portraits of R.F.K.) and an eclectic lineup highlighted by the Gram Parsons lineup of the Byrds.
