People collect stamps, post cards, beer mats and, um, even vintage radios
, so why not QSL cards? I have received some fabulous ones that must have cost a small fortune to produce in a time when many run of the mill ones were still printed letterpress. They all relate to my amateur/SWL operations which of course do make them special to me. This has reminded me that perhaps I ought to get some of them out of the box and perhaps make a framed display. (Another job for the round tuit pile... ?)
