Original 1st printing 11 x 14" concert poster (small black & white version) for the Grateful Dead appearing at the University of Iowa Fieldhouse in Iowa City, IA on 2/24/1973.
Art by S. Ross, medium-thick flat index stock poster is in BEAUTIFUL mint/near mint to near mint (A/A- to A-) condition; a very crisp/sharp example of this low-run regional Midwestern Grateful Dead concert poster from a semi-obscure 1973 college show.
