Topic: Large mushroom lamp shade - Art Deco? Scottish?

Yes, now that I look, they have been described as being 1920s or 1930s. The more cautious describe them as 'vintage', whatever that means. However, a French dealer who was selling a rather splendid pair of Art de France lamps dates them to the 1970s. That seems more believable.

'70s in the uk included design companies such as Biba and Laura Ashley and all sorts of stuff that would be perfectly consistent with this nouveuau-ish revival style.

Lots of us went a bit bohemian and started climbing Stairways to Heaven, rather than going teeny bopping with the Bay City Rollers, back then.

I can remember going to the major International wholesale gift shows in the 70s and seeing a few lamps and fixtures very similar to these. They were never really inexpensive but were not really high priced. I don't recall them ever being marketed much in the U.S. by any large chain/big box stores but they were more apt to show up in designer and antique shops.
There were also a few that had dated back to the 1930s as has been noted here. Trying to determine what was old and what wasn't was not easy.
