Looking For Help Identifying A Printer (Or Publisher) Logo.

I've recently acquired this postcard:






I'm attempting to identify the printer (or publisher?) logo in the lower left corner. Here's a closer image:



I've found one other example of this card online and the owner indicates it was postmarked in 1915. I've been able to locate other examples of cards with this same logo, all seemingly from the early 1900s. I suspect it's a printer logo (rather than publisher) because some cards with the same logo list a publisher, but not all of them.

Thanks ahead of time for the help. :)

Try the 4th entry down, from Section IV on "Identifying Publishers and Trademarks":

From this book:

Wow! I'll be honest, I wasn't expecting such a quick answer.




This looks like a book I need to try to find a copy of! Though, in a quick search, it doesn't seem to be super common.

Thanks again!

The postcard club in New York used to have an excellent site, with a really good guide, but that seemed to die a death.

Perhaps the guide will be revived via their new website -

Was it at that same URL or a different one? With the correct URL I can hunt for it on the Internet Archive.

EDIT: Nevermind, I found it. :) https://web.archive.org/web/20220405094722/http://www.metropostcard.com/metropcguides.html
