Bruz: This is a commemorative brand available only to the workers & clients of the Cuauhtémoc Moctezuma brewery! The edge of the label reads: "Cerveceria Cuauhtemoc Moctezuma comparte con sus clientes esta edición especial de cerveza 2006. Gracias"

Thanks out to Tesguino for the bottle! Technically, you're not allowed to ship glass out of Mexico, so I'm lucky to even have received it empty
