Mid Century hand painted, gilt, signed lamp

Hi all. i got this pair of lamps at Goodwill and they are signed Murai plus a first initial I can't make out. They're hand painted and gilt. I had to have them but can't find any information about them. They have the original green felt on the bottom, so I don't want to remove that to look for a manufacturer. One of the lamps has 2 bands around the neck, the other has a single band.

Also, can someone point me to . resource on how to preserve / clean these lamps?
