Catalogue for postage stamps or coins - has pockets containing cards carrying information revealed through slits in pockets

摘要

A catalogue for postage stamps or coins consists of a number of pockets (1) made of plastics or cardboard. Each pocket (1) has a side flap (2) with a dovetail groove on one side and a matching tongue on the other side enabling a number of pockets to be linked together. Each pocket contains two cards (6) one of which can be pulled out through the side of the pocket and the other can be pulled out through the top. There are horizontal and vertical slots (5) cut in the pocket (1) through which the formation on the cards can be read. The card (6) have finger grips (9, 9a) for ease of handling. This form of catalogue is more compact and easier to read when compared with the usual bulky catalogues.
