Convention Center Las VegasExtremely rare August 25, 1967 17. 5" x 22. 5" concert poster for show at the Las Vegas Convention Center. Handbills with this design, and a poster with another design have been found for this show, but this design in poster form has never come up for sale. It is the first one we've seen in almost 50 years in business. Moderate restoration including cleaning, flattening and minor repairs (see photo no. 3 for before restoration).
