A contemporary pocket memo holder version of the “Add-A-No” apparatus, handsomely fashioned from leather by England’s Roy Roth. It’s designed to hold a single 3 x 5” file card on the right panel of the opened case. The pocket on the left-hand side contains an envelope large enough to hold a file card. Designed similarly to the well-known Himber Wallet. Includes a booklet with many routines. Very good condition.
