Ron (and anyone else with an interest in 100 year old cancels on narcotic stamps),
Quote:
Were there no handstamp provisionals used in Chicago?
No, I don't believe so.
However...
According to this entry in a 1919 publication:*

Provisional handstamped narcotic stamps were available in Peoria, Illinois.
According to Mr. Google:

The distance between Chicago and Peoria was a few hours trip a century ago, so it is not inconceivable that Chicago-based manufacturers and depots did use provisional narcotic stamps.
Alas, there is only a description of the handstamp that was used, and no measurements of the "Narcotic" design.
So, at this point, there is a list of manufacturers and some images of their initial cancels, and a description of the provisional handstamp.
Maybe someone has an example that ties everything together?
