Antique Tequila Bottle Does Anyone Know About De La Guera Tequila?

Does anyone know about De La Guera Tequila? - antique tequila bottle

I bought an antique (c 1820) buffet. In a drawer a bottle of tequila De La Guera with the stamp duty was in 1972. The label also indicates it was made by Seagram's in Mexico. This is a Tequila Añejo.
