The Lamp above is one I showed you last week, I removed the shade and tried to get a shot that would show you the glass chimney is blue glass and really thick. There are no markings on this lamp, but the blue base and chimney have bubbles in the glass, it is very thick.
I believe it to be from the 1800's
I have searched for the lamp and this link shows hand blown glass from the 1800's. it is much like some of these.
I love it so it doesn't matter to me.
The above is a lamp that has been wired for electric, it is almost identical to the one below. They are marked and though very much alike, are different brands.
The first lamp lives on my dresser, the electric one is on my bedside table and Bob gets the oil lamp on his bedside table.
Yes I did PLAY in PicMonkey with my lamps.
These lamps are flea market finds when Bob and I got married in 1985. The info here is the markings on the lamps. I have no history for them.
