The comparison of round-hole perforations is discussed in terms of a case involving threatening and obscene anonymous letters sent to a young girl. The disguised, block style hand-printed letters could not be successfully compared with the suspect's normal handprinting. The last communication to the victim was a handwritten letter, subsequently identified with the suspect. A comparison was made between the postage stamp on the handwritten letter, now of known origin, with the postage stamps on each of the six anonymous letters.
