I always peruse The Bay for classic remainder lots and collections in search of socked on the nose cancels and other interesting stuff. I spotted this collection offered for sale, a few things caught my eye, and I made an offer.
There's the usual amount of damaged crud, but the person who assembled it appeared to have an interest in overprints, perfins, and cancels.
There might be some better stamps sprinkled throughout as well.
Regardless, it will be a lot of fun to dissect.
Too many images to list on the forum, but I threw together a web page. Images are configured to display at 100% of page width, so if you maximize your browser window size, you'll see the images at higher resolution.
Apologies for the clipped stamp images at the edges, but the stock pages were larger than my scan bed.
