Note: Each 60-page comic consists of a color cover, a blank inside front cover page, 56 comic story pages consisting of only 1-2 illustrated panels each in black & white, a blank inside back cover page, and a final advertisement back cover in color from the publisher for other adult titles. Publishing dates are estimated as 1977-1978 based on the Depósito legal # entries on the indicia, as there are no cover dates or copyright dates anywhere else within these comics.

Note: The MATA RATOS second series contains more adult humor, cover girls, assorted nudity, and rotating comic stories and cartoon features from many creators.

Note: Also referred to as 'Seleccion Romantica'. This was the title on the covers in the early issues (although 'Romantica' was always much more prominent). The indicia listed only publisher information, not the title of the series. 'Seleccion' was eventually dropped from the cover title and the series is often referred to as simply 'Romantica'.
