This is a late 1800's turn of the century handbill for an entertainment show at the J.E.B Stuart Camp Confederate Veterans No. 14. This came out of the estate of Confederate veteran Ambler B. Moncure who also performs in the program advertised as a female impersonator, his name is on the handbill. Handbill measures aprox. 5 3/4" x 9" and in excellent condition. I've also included an envelope from Ambler Moncure. Buyer pays $4 ph, International Canada Hawaii Alaska pays actual postage.
