TLS from the legendary American theatre producer to the treasurer of the Majestic Theatre regarding a change to box office policy concerning tickets purchased with a charge card.  July 27, 1981;  1 pp. on A4 personal stationary.  In part, "I want all tickets ordered and/or paid for by Charge Cards to have the appropriate Charge Card presented at the box office window at the time the tickets are picked up, so that the purchaser's signature may be verified."  Mailing folds, else fine.
