Two packages of index card guides sitting on a library card catalog next to a gray Royal typewriter. The manilla package has 4x6" guides and the 5x8" guides are in blue pressboard.

Oxford seems to have quit manufacturing the 1/5 cut tabbed 4 x 6 inch index card guides, but yesterday I scored a bundle of 100 along with some 5 x 8 inch A-Z guides. The big win here was that the lot came for a total of $3.50!
