Original 1st printing 14&3/8 x 18&3/8" concert poster for late-'60's Michigan hard-rock band the Frost recording live at the Grande Ballroom in Detroit, MI from 8/6-7/1969 (supported by All the Lonely People (8/6) and 3rd Power (8/7)).

 Artist unknown/not credited, image is # 97 in the Russ Gibb Presents/Grande series (G/G-690806-OP-1 in the Eric King guide). 

 Medium flat index stock poster is in near mint (A-/B+); condition; nothing more than a whisper of handling and a minuscule nip tear/pressure crease in the lower right margin, otherwise it is a VERY clean example of this late-period Grande Ballroom poster.
