This is a very common item.  Comes in a large number of colours in clear glass as well as in the milkglass and in a large variety of shapes and sizes.

Replacements.com says this was manufactured between 1934-1965.  But here is a little mystery as it is signed with a weensy anchor that Glass Lovers database says is dated Anchor Hocking Newell Specialty Glass 1987.

So…..I had to find out a bit more about this discrepancy.  At the Anchor Hocking Museum there is a history of the company and its many iterations.  Included isthis information:

“The Newell Corporation acquired the Anchor Hocking Corporation on 2 July 1987. With this renewed influx of capital, several facilities were upgraded and some less profitable facilities were either closed or sold. The Clarksburg, West Virginia, facility was closed in November 1987, Shenango China was sold on 22 January 1988, and Carr-Lowry Glass was sold on 12 October 1989. Today, Anchor Hocking enjoys the financial backing and resources as one of the 18 decentralized Newell Companies that manufacture and market products in four basic markets: house wares, hardware, home furnishings, and office products. You may recognize such familiar Newell Companies such as Intercraft, Levolor Home Fashions, Anchor Hocking Glass, Goody Products, Anchor Hocking Specialty Glass, Sanford, Stuart Hall, Newell Home Furnishings, Amerock, BerzOmatic, or Lee/Rowan.”

Perhaps this line was produced when the company took over the Corporation in 1987.  Check out the Museum.  It is a private museum and has an interesting history of its own.
