Need your point of view for booklet BK52, Cameo issue 5 ¢ stamp (405a pane of 5)
BK52c is a Type III with a 62mm wide front design. Inside cover inscription: 'Give stamp to shut-ins'
BK52d is a Type IV with a 65mm wide front design. Inside cover inscription: 'Give stamp to shut-ins'
Mine has a 63mm wide front design, i'm right in between but what would be the appropriate identity for this ?
