Set of Lamps: Hand Painted Porcelain

 I have a set of 2 lamps with no shades. Look to be hand painted porcelain. I can't seem to find any marking or logos or names on either of these.  Both of them are electric and have a felt bottom on them. One is green felt while the other is brown.

Not sure if there is a name or anything under the felt, as it's stuck to the base of the lamp pretty good I may destroy the felt if I attemp to remove it.

Anyone have any idea what kind of lamps these are and what they may be worth?

Thank you!
