Vintage Quezal Iridescent Pulled Feather Art Glass Shade Ruffled Edge Signed For Sale

Up for sale is a signed Quezal glass lamp shade in very good preowned condition. It doesn’t have a cracks but has a tiny chip or rough part on the bottom part ( fitter collar ??) that goes into the lamp. It is almost a rough spot that does not have a crack ( see last photo) can’t see it when it is in the lamp. I didn’t try to clean the glass and it has some marks, the worst being the second to last photo. Some marks look like they were in the glass when being made. I took all different side of the glass so you could see any marks/ condition. Around the area where it goes into the lamp it looks some gray from putting it into a metal lamp ( see that on the last two photos). I am trying to point out everything but when using the shade you really can’t notice much of it. Please see photos for measurements. Please enlarge photos as they are part of the description. Thanks for looking and please take a look at my other items, I combine shipping within the USA.
