Given that I collect Machin stamps by postmark, I spend a
lot of time sorting Machin kiloware. (When I get up to 50 posts -- very soon! -- I'll start making trade offers. They'll either be my picked-for-postmarks-but-not-varieties Machins for
more Machins, or my U.S. or World stamps for Machins.)
Anyway, I found this simply amazing cancellation. I am going to reproduce it on the cover of my in-design-progress album, and mount the actual stamp on the first stamp-bearing page. What do you think?
