Christlieb Lithographs Lion and Horse

     I have these lithographs, that I just got at auction in a boxed lot of pictures, all I've been able to find out is that the artists are known for their paintings of carousel horses (and other carousel animals) and that they do very detailed work based on images of real carousel animals, both of them have their certificate of authenticity, and a small paper telling about the carousel animals, including when they were made, where, and by whom. I would love to learn any more information anyone has on these including their value, as they will be for sale, but not until I find out what they're worth, thanks in advance for any help!

(Sorry, the pictures really don't do these justice, they are in really nice condition, but they're fairly shiny, so I had to photograph them in lower light to relieve glare. And if anyone is interested in purchasing these please feel free to contact me at [email protected])
