Here's something that you don't see every day (fortunately): an old cinderella label that has been (badly) reperforated.
The perf. 11 1/2 varieties of these Hotel Sherman stamps are quite scarce. Not all color combinations have yet been seen. The rouletted versions however are quite common (see below).
Not sure why only three of the four margins were reperforated on this example. Maybe the reperforator-guy* got tired?
