TLS, one page, 8 x 10.5, FBI letterhead, May 27, 1958. Harsh letter to an FBI employee. In part: “You incorrectly routed an incoming letter to another division although the communication in question had not been acknowledged…There was no excuse for your carelessness on this occasion. Hereafter you must exercise greater thoroughness and more careful attention to detail in the performance of your duties so that you will not again be chargeable with such a mistake.” In fine condition.
