I'll politely disagree with nick2601. Eyup Sabri is a known name among collectors of Turkish meerschaum. Though Ismet Bekler was the first, Sabri was the second or third carver to sign his pipes (I don't know if Ismail "The Artist" Ozel started doing so before or after him). He was the only Turkish carver I know of to use horn stems, specifically water buffalo horn. Your "Adam & Eva," and possibly the skull, have them; the others are plastic. Some of his pipes also came with a tamper having a carved meerschaum handle.
He's right that Fikri Baki is probably the best non-figural carver working today. The late Eyup Sabri was one of the, if not THE, best now-gone Turkish figural carvers. Bekler carved incredible free-form pipes, but I think his figurals and heads weren't always top-notch. He also, later, carved a lot of relief floral work. But Sabri's floral and relief carving was spectacular. Carvers like SEvket and Tekin developed their own incredible relief carving style, but they owe some of that inspiration from Sabri.
I rarely see Sabri pipes on eBay. When I do, they usually get listed for at least $150, and may fetch $250+! If you can sell on eBay, that'd be my advice. These are really great examples of Sabri's work. At any given time, there may be ten or more Beklers listed, and there are over 18 now. There are two Sabris listed. Check eBay's closed auctions to see what his work can sell for!
