The Mexico Exporta Definitives are a collector's dream. The stamps are beautiful, and were printed in an array of designs, papers, tagging, colors, and perforations. There is a comprehensive listing of these stamps at the etiangui site. Covers of this issue are hard to come by. I break down this issue into four major installments, and have finally gotten around to adding pages for each of the four major groups (which are broken down into a dozen or so issues by specialists more well informed than I am), and below I also have links to pages for each design. I am missing a few major varieties, but I think I have all of the base stamps by now.

Quick links to the issue pages: The Air Mail Issue 1975-1982 / The Ground Issue 1975-1982 / The 100's Issue 1983-1987 / The 1000's Issue 1988-1993

I came across a correspondence of this issue in 1992 composed of approximately 100 covers, mostly from Mexico City, and all to Chase Bank, in Miami, between 1989 and 1992. I have described some of these covers in articles 8 (the high values), 29 (focus on the 5000 Pesos Algodon), additional material in article 34 (10 Pesos Tequila), and an article dedicated to the oval cancellers found in this correspondence (article 58). These oval cancellers can be grouped into several types (D.F. stands for Mexico City, 'Distrito Federal') : ADMON DE CORREOS D.F. 20 / Santa Clara ; DESPACHO Y RECIBOS : D.F. 7 ; REGISTRADOS : D.F. 3 / D.F. 11 / D.F. 19 / D.F. 21 / D.F. 28 / D.F. 53 / D.F. 77 / San Luis Potosi 78000 ; REGISTRADOS INTERNACIONAL : D.F. 9 / D.F. 19 / D.F. 58 / Leon / Merida 97000 ; REEMBOLSOS : D.F. 17 / Merida 97101
