Humorous Town Name Cinderellas

Can someone tell me the source of these Humorous Town Name Cinderellas?

They were published and sold by Western Stamp Collector in 1938/1939. They started with a series of 20 which was continued through number 40.

John Coulthard, philatelic artist/cachet maker did the drawings

It is difficult to put together a complete set, although not expensive, a complete set of 40 recently sold on eBay for $39.95.

There appears to be a single addition to the set of 40, a label numbered (00), but I don't know how it fits into the original series.

I also collect these labels on cover postmarked from the towns they represent. Also a challenge to complete.

Nicely solved!
esp. the IC (or JC) monogram on the labels

Thank you "DonSellos" and rod222 for the information. My only interest are the Texas towns for my Texas Cinderella collection. I'm sure subsequent readers will find your comments quite helpful. Jeff

There is currently a group of these for sale on Ebay
