These are a pair of Paul Hanson hand painted lamps. The lamps work and do not seem to have any defects except minor discoloration from age.

I'm curious as to what the value of these are? I've looked everywhere online and can't seem to find a pair like it, but have found many other Paul Hanson lamps. 

Any information you can give would be appreciated!

Unknown signature and marking on the back. Beautiful ceramic tray with a blue/green agate pattern.

Hand painted hurricane lamp. looks like original electric cord. The lip of the lamp has a chip about 2 inches wide by 1/4 inch. You cannot see it with the lamp assembled.
