Re: What was Ginsburg & Klausner, S Fallsburg, NY (Catskills) not listed as hotel #usa
A very extensive web site about the Catskills is the following:
There is a list of hotels and bungalows for each town. I did not see the Belveder listed under Fallsburg/So. Fallsburg, but I suggest that you explore the web site for yourself - it is also possible that it was in another nearby town.
For anyone interested in this topic, they are still collecting photos, information, etc.
