Either way, that dancer is more valuable than the vase. If you find out who the maker is, I would start it a bit high and auction it. It looks "homo-erotic"...I would be shocked if it is worth less than $200.
In my research on the dancer that this type of artwork is very popular with Russian collectors; especially the one's featuring dancers from the Russian Ballet. Those have set records in the 6 figures. But I doubt this one is worth anything like that
Congrats on finding such exceptional and quality, Art Deco pieces!!! I've dealt in and have collected them for years and they garner top prices! Do your research very well on these as you don't want to lose a LOT of money if you sell them!!! Also there are many collectors all over the world who collect certain periods within the Art Deco movement who will pay more than what the listed value is as well.
