Only one set is pictured. The other three sets are identical to it. All appear to be new and unused (most glasses still have the original labels on them, see photos for example), but the other three sets have not been cleaned, so they are a bit dusty after several decades in storage.
Beautiful colors & patterns, all in fine crystal.
They're gorgeous and deserve a chance to be used and celebrated! I have no recollection of these ever being used (we are non-drinkers.).
