These are vintage, hand-blown glasses from Tlaquepaque, Mexico, with a beautiful deep blue color. This is a set of 5 glasses. My family likely purchased these about 50 years ago when they traveled to Mexico. Judging by the paper labels, they were probably used only a few times. The paper labels remaining on the bottom have been left as they are, without being forcibly removed. The label information, as far as can be seen, is as follows: • VIDRIO TLAQUEPAQUE • HECHO EN MEXICO (Made in Mexico) • PICO (Workshop/Series Name) • PROD. A.ABUNDIS (Maker/Workshop Name) The height is approximately 14.3-15.4cm. Due to being handmade, there are individual differences, which is part of their charm. There are no cracks or chips. Thank you for looking.
