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!
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"
