vintage hand blown Mexican glass tumblers, cobalt blue swirl drinking glasses, 70s 80s retro

Lot of six vintage hand blown glasses made in Mexico... all cobalt blue, each slightly different, in a couple of  different 'patterns'.

These are rustic and simply made, one has a makers flaw chip to the rim. The height varies a little on these glasses, they range in size from about 5" to 5 1/2" tall.
