My mother-in-law just showed me an old strop she has and I am curious if anyone here is familiar with the manufacturer.

One side is leather and the other is linen. The linen side has "IRISH LINEN" and "SILK FINISH" imprinted on it. The leather side has "A-1 EXTRA HEAVY SHELL" and "151 VALENTINE & YULE BARBERS SUPPLIES CHICAGO, IL" imprinted on it.

So, what do you know?
