Picked up an old collection of famous classical pieces at a music store on a trip to the coast this weekend without actually checking when it was published. Flipped through it today to try a few pieces and did a double-take when it referred to Rachmaninoff as "one of the greatest living pianists and composers" (I was pretty sure he was long dead, and indeed he died in 1943). Flipped to the front of the book and it was published in 1936!
I'm not totally sure if that's also the printing date, but regardless it's clearly pretty old and in dang good shape. I found it on the Internet Archive, in case you want to check it out yourself: https://archive.org/details/robbinsmammothco00frey
