MASSIVE WORLDWIDE MACHINE CANCEL COLLECTION. couple thousand covers in 13 binders, tracing the evolution of machine cancels over the first few decades of the 20th Century (remarkably little modern material), note dedicated binders for Austria, Belgium, France, Great Britain, Italy, Mexico, Netherlands, New Zealand, and Switzerland, as well as a three-volume A-Z collection of most other nations, generally fine to very fine, an extraordinary lot which would be perfect either further study or for breakdown by a postal history dealer, sure to be better items throughout, a wealth of interesting material
