Expo Cancel

Hey. This is fun. I'm learning how to post scans and I'm just showing some things that seem interesting to me. I hope its OK to do this.

Absolutely!

ronv, Greetings:

Within the past 24 hours, I shamelessly posted a Pakistani aerogram I know nothing about, so go for it!

Hint: if you want to look more like a 'player', google the expo, and co-post the wiki link.

BTW: Flag cancels are a collectible topic, in & of themselves.

A shame that it is a cut down piece. That's a relatively scarce marking (an advertising slogan for the Panama California Expo), valued at $40 in the Flag Cancel Encyclopedia on a VF cover. There were quite a few slogan advertising machine cancels for the Panama Pacific and Panama California expositions; interesting area.

Well that is interesting. Thanks for that info paperhistory.

The WikiGod says that the Panama–California Exposition closed 01/Jan/1917.

Santa Monica is >100 miles north of San Diego; perhaps the news hadn't reached them?

Hi Ronv,

The widely respected source for expo markings is Bomar and in his catalog of expo markings, yours is recorded as "SD16-06" and he has a value of $16 on card and $35 on cover with double for 1917 use.

The earliest known use of this cancel is 9 March 1916 and the last known use is 8 January 1917. The version of the catalog I'm using was updated in 2007 so the values ought not be too far adrift.

best,

Larry

Larry is right that the Bomar catalog (the 3rd edition of which is only available on CD) is the standard for exposition markings as a whole. The Flag Cancel Encyclopedia and other machine cancel literature sometimes provides useful supplemental information, most notably Payne's "United States Promotional Slogan Cancellations 1899-1940."

One of the many accumulations I am gradually working on in hopes of an eventual exhibit is a group of the various 1899 slogans, as the birth year of the slogan cancel. Some day...
