There are thousands of pieces of vintage sheet music available for collectors and curiosity seekers. Prior to the 1930s, a large percentage of them had wonderfully hand-lettered titles on the covers, but gradually there was a shift by music publishers to utilizing metal type for the bulk of their output. Normally set in an all-caps format, certain type faces reappeared in growing frequency and familiarity. Composer JNL is one such example of a “workhorse” font, and has been re-drawn and reinterpreted by Jeff Levine Fonts in both regular and oblique versions. It is based on the design "Glamour", released by Lanston Monotype in 1948; which in turn was based on "Corvinus", designed by Imre Reiner.
