Almost all issues are represented, with Small Queens, Leafs, Numerals, Jubilees, Maps, Edwards and even saw an Admiral with a very partial Hamilton cancel. We note a great variety of different towns in this lot, and a high percentage are well struck, with many hundreds of stamps in all. We scanned many representative pages online to give a good taste.
