AO-U680, 2015, Bank Swallow, First Day Cover, Add-on Cachet, Standard Postmark, SC U680, Postal Sationary
As you know USPS delivery time very a lot these days. Please let me know if you have any issues before opening a Case.
Add-on cachet is:
A cachet design added to a
cover which was originally uncacheted. An add-on cachet should be
identified
by maker and date (mine are stamped on the back with the date) so that it is clear that it is not
contemporary with the cover.
