I recently purchased a Blue Scott International Volume 1 where the previous owner obviously had chosen stamps for the U.S. section with an emphasis on cancels/precancels. I thought some of you might enjoy seeing a few of these. As far as I know the 19th century ones aren't out of the ordinary (geometrics and registered cancels) but there are some unusual 20th century cancels (I have no idea whether all of these are genuine or not--not my field).




I particularly like the hat cancel on the 8c Sherman!
I'll put the rest of the cancels in a second post.
