Here is a photograph (and accompanying press release) that I recently bought on ebay. The picture is of bandleader Kay Kyser, and his comedy sidekick, Merwyn Bogue (a/k/a “Ish Kabibble”).
The picture, from NBC Television, is dated December 25, 1949; Kay Kyser’s TV show, the College of Musical Knowledge, had made its debut, on NBC, a few weeks before.
