This parcel tag was sent from Mr. A.A. Perkins involved with Operation Ivy. His address: Taskgroup132.1 Bureau of Ships, APO 187 San Francisco.
Operation Ivy was a nuclear testing programm conducted at the Enewetak Atol in the Marshall Islands in October/November 1952.
The parcel (containing a plant???) was sent to (probably) his daughter in Albany, California.
The parcel passed the "Plant Quarantine in Alameda County Agricultural Commissioner". See marking upper right of the tag.
The tag is franked with a 4c and 20c Prexie. Handwritten on the tag (left of the 20c Prexie) is the numeral "24". The APO 187 cancellation is October 2? , 1952 (exact date in October not readable).
Who can figure out the rate? Tony W's Domestic Postal Rates book does not give me the answer (page 225).
An interesting puzzle.
