set of 8 colored cordial glasses

Sure enough -- after I showed all those shot glasses last week, I found this box again -- and 'cordials' is just a fancy name for 'shots', so here they are too?!! ;-) :-) These eight are all the same shape, a pair each of purple, amber, and blue with a single green and clear one. (mebbe those last two used to have 'seconds' too, I don't know?) They don't appear to be top quality, having a few irregularities between 'em and little random bubbles in their glass. They aren't marked, I don't know how old they are or who made them, I think they were found at an estate sale somewhere along the line.
