Carl Kress

Though many collectors focus on instruments in fine original condition, every so often one emerges that, regardless of condition, is no less exciting than a paleontologist finding the “missing link.” Everything there is to know about the Gibson L-5 designed by Carl Kress can be learned from this example, with the model designation “Special” hand-written on the interior paper label, all of its original parts, and serial number 89849 (consistent with a manufacture date of 1933).
