I found a stuffed animal in my attic of a masked mouse with a label having "Schwartz Toy Mfg. Corp." on it. The spelling differs from FAO Schwarz, and I can't find much on Google except a few sites selling vintage toys. Is "Schwartz Toy Mfg. Corp." the same company as FAO Schwarz, or perhaps a knock-off? The item looks pretty old and feels like it's stuffed with a harder material than today's plush stuffing. I'd like to find out more about it, but definitely interested in the company if it's not FAO Schwarz. See images below.
I contacted the Astoria Historical Society, as suggested, and here is their response. The search continues!
First thing is that it has a zip code so the toy was made after 1963. today would be zip code 11106 which would be the area called Ravenswood.
I quick look up shows that the company was made in Brooklyn 32, which today is 11232 - the Bush Terminal area.
I have no further information - there are old phone books in libraries that could help you find an address, but I would suggest discussing on on one of those forums that have sprung up on the internet which discusses just about anything. There must be a 100 discussion groups on toys, and they generally welcome inquiries and help searches.
Good luck! You find anything do share it with us.
