I'm not going to post all of the small revenue documents (checks, sight drafts, etc.) I obtained at or around Chicagopex, as that would be far too many images. Instead I'll just post the most interesting or aesthetically appealing (to me).
And lastly a set of 4 checks in different colors from the National Bank of New England, all with (nominally) illegal usages of 2-cent proprietary stamps as documentaries... and the purple check is signed by someone with the last name of Purple... go figure.
Very nice stuff Dan. I'm sure you are aware of the American Society of Check Collectors, but other folks on this board, if they are interested should visit https://asccinfo.com Go to the Reading Room where you can find past issues the The Check Collector as pdfs. I'm sorry to hear they will be ceasing publication because of the lack of a new editor.
