Oh yeah, she was a stripper. No doubt about that, just most famous for only stripping off one glove. 
Burlesque was probably most popular in the 40's, but became less popular when the modern style of stripping came in. Back then it was a mainly male audience (though at the same time you had the Revues which were the upmarket version of Burlesque and which catered to a more even mix of men and women).
New Burlesque began it's revival, in the 90's I believe, as a reaction against stripclubs - with the idea of women not having to remove clothes for sexual titillation. Whether or not it is an effective reaction is another story. It was also a reaction against what is seen as an attractive female figure. So while the original Burlesque stars were usually of a fashionable physique. New Burlesque performers can be all shapes and sizes. (See Dirty Martini for example)
Unfortunately the more attention it gets the more places spring up which take Burlesque back to being only for certain body types, and they also tend to take it away from comedy and a parody of what is seen as sexually attractive.
rebecca most performers dont make much money. And SM is right, money doesn't mean it is art, just profitable.
Just to make this clear, I don't care who does and doesn't like Burlesque. Just wanted to correct some misunderstandings.
Now what have I missed while I've been typing..
