The glasses hold 8 ounces and the pitcher holds 56 ounces (I think).  Can’t say that I have actually measured their volumetric capacities.  Very technical language, n’est-ce pas?  These are pretty common pieces, see them all over the place, although this was the first time I had seen glasses and a pitcher together.  I bought them at an auction in Orono for a pretty reasonable price.  Used them for Christmas O.J., but the glasses are hard to get your hand into because they are narrow.  These are Depression pieces.  Depression glass, although old, is still readily available as many pieces were very solid, unlike some of the finer crystal.  This comes in other colours as well, but I don’t think that the coloured pieces are as commonly seen.
