Poster Stamps
of the Chemical Industries Exposition
(Click on any image to see a higher-resolution version.)
Cinderella stamps. A Cinderella stamp is essentially
any stamp not produced by a government for use as postage, a definition which includes
(to some people) officially-issued stamps such as tax stamps, telegraph stamps and
locals. Poster stamps are advertising stamps, and usually poster-like in their
appearance. Many are indeed just reduced versions of actual posters, and were issued in
conjunction with the events for which the posters were produced. The poster stamps
on this page were all issues in conjunction with the Chemical Industries
Exposition in the U.S.,
now called "Chem Show". One even thas a train!
Below are all I have been able to accumulate so far. Thanks to the history
page of the organization that runs the show, I was able at last to assign reliable
dates to the first two.
I find it interesting that even as late as 1963, the Exposition was still
showing factories belching polluted smoke into the air. I wonder when they
dropped that image?
The stamp below may be a precursor to the series. It's interesting
to note the way new technologies are grouped at first, then
assume identities of their own. Early auto show were often combined
with shows for electricity, for example.
