Need Help To ID Printer's Logo On This Postcard

Who printed this card? Whose circular logo is this?


c1910, U.S. city view.
I have looked at the standard postcard websites which list all sorts of information about countless publishers, but none seem to list this logo.

What's on the other side of the card?

"Circle, dark with 3 white quarter moons inside......"

Patg.
Thank you! That seems to be the perfect match, and further confirmed by several Grollman-marked cards on eBay with the same logo. Another book I need to add to the library!

DeeBee,
A fair request. I suspected a national-level publisher and did not want to bias the initial responses. The other examples I had handy were all used from Illinois (two generic greetings) and Indiana (a city view).


Searching further, I see an article on Barr's Postcard News site which says "... photographer I. Grollman of Chicago"

John,
This one is copyright 1975. Don't know if any newer.

Saw one on eBay for ~$14. (Went back, and it's gone)

Pat

I just bought that copy, before I made the above post. Way ahead of you. Thanks.

When I read the first post, I thought
"That's not going to get cracked"
How wrong was I?
Amazing ID !
