Nice little lot. It wasn't cheap by any stretch, but a nice variety of material. Many of them are fairly inexpensive. Most of the cancels I already have, but the main reason for buying it was the last four pages, all 3-cent and 4-cent types with Proprietary cancels. Some of these I have not seen before, so that made it worthwhile.
One nice potential bonus when it comes to proprietary cancels: because they tend to be late dates with respect to the range of first issue usage, the possibility of silk papers is increased. Once I start breaking it down, that's something I will be checking.
Sellers pictures, so not the greatest detail in the world. The writeups are the seller's as well.
