1.25" no maker or back paper. Oxidation on metal back, stain on cello surrounding the collet as well as over most of the front which also has two cello cracks below "Jim", one at base of his hair, one about .25" long  below his chin plus a few near microscopic tiny craze lines. Cracked areas can also be very slightly felt to the touch  as they are a trifle raised. Still with full gloss and only example known to us. Good. Rare. Paul Muchinsky Collection.
