Four (4) Riviera Blue Colony WHITEHALL ice tea glasses

Description

Here's four (4) 13-ounce ice tea glasses, which I believe were made by Colony Glass (who had acquired the molds from Indiana Glass, I believe).  The pattern name is 'Whitehall', though some people refer to it as 'Whitehall American', since it's really a knockoff of Fostoria's 'American' pattern (and gets mistaken for it often).  I've gathered from elsewhere that this color is called or is at least referred to as 'Riviera Blue', and I'd guess it was produced in the 1960's and/or 1970's.
These four glasses are a little over 6" tall and are about 3-1/2" across the top (the foot's about 3-1/2" in diameter).  They hold exactly 13 ounces when filled to the brim (more or less), so 'functional capacity' is 11 to 12 ounces.  All four are in pretty good shape, but all four have water stains on the underside of the bottom (pretty common for glasses like this, when after washing water collects on the underside of the foot).  They're still perfectly functional and would fit perfectly into an existing set (you're not going to see the underside unless they're upside down).  I've got no use for these and have way too much of this sort of thing lying around (and can't keep myself from buying more), so these need a new home.
