Pi Day is the perfect date to publish this piece of mail sent by Phillip (the USA).
The shadowy stamp is dedicated to Women Cryptologists of World War II. You can read more about the stamp here and here. I love especially the First Day of Issue pictorial postmark. It includes a a coded message that contains the date and location of stamps issuance: October 18, 2022, Annapolis Junction, MD20701.
Great postcard and stamps! There is a pizza place near my house advertising pizza slices for $3.14 on Pi day!ReplyDelete
