Auxiliary mark: Postal marking applied to covers by handstamp, machine cancellation,
a stick-on label, manuscript markings, or by mechanical or electronic methods such as
addressograph or computer, indicating that the covers were given special attention due to
some special circumstance.
This work was originally prepared as an interactive presentation given to the
Rochester Philatelic Association
on March 25, 2004 using a laptop computer and Proxima projector. As such, minimal text is
found among the pages now online.
Come explore some of these markings and their covers!
