I found (on ebay) & purchased this cast iron, notary embosser and the stamp reads”Charles Chaplin Advertising Service Company Corporate Seal Illinois.” ( pictures attached)

The actual seal press I found / purchased was being sold as just a ” Antique Notary Notarize Notory Public Cast Iron Tool Stamp Seal Logo Embosser”
but when I read the description >
“This is a metal, cast iron, notary embosser type tool. It works very very well, and when used, “stamped” it stamps, the following on paper: “Charles Chaplin Advertising Service Company Corporate Seal Illinois.” As you can see if you will look at the pictures closely, this item has “B7-96” scratched on the side, and it also says, “Dwight & M&H Jackson Corporate Supplies.”
After reading the description I did some research / detective work >
The stamp matches exactly to the one I found on a 1915 stock note that was on the charliechaplinarchive.org website plus the company who made or distributed the stamper is the same name as the company who provided stationary for Charles Chaplin Advertising Service Company

The info and pictures of the stock certificate with the seal and the and the staionary company’s reorder form were found @ http://www.charliechaplinarchive.org/ricerca
