I scored a Zverev Russia catalog for $20 plus tip and shipping which still makes it cheaper than an eBay
purchase. Not to mention that this really hard to find catalog is only available on the Bay from Russian sellers shipping from Russia which is a massive issue now given World events.
It is written in Russian and priced in Rubles but the illustrations are fantastic and mostly self-explanatory. A must have for collectors of pre-1940 Russia.
