Back cover
Starting in 1941 the back covers of issues from the "Las Grandes Aventuras" and the "Los Albumes Preferidos por la Juventud" (Colleción "Audaz" & Aventuras y Misterio) printed various collector cards, which could be glued into different collecting albums. These folded "Álbumes Centella" sheets could be ordered free and measured 17,5x25 cm.

Note
The "Las Grandes Aventuras" (or other series by Hispano Americana) have no numbering or date printed on the cover or inside, thus making it difficult to make an index in chronological order. Fortunately, most of the back covers from the series "Las Grandes Aventuras" and "Los Albumes Preferidos por la Juventud" series (Colleción "Audaz" & Aventuras y Misterio) have a back-list and an ad for the next issue. Sometime also the current or next issue for the other series.
Comparing the back covers of the first print issues prior the first Mandrake issue it is possible to make a list which shows that the first Mandrake issue was #56 in the "Las Grandes Aventuras" series, most likely published in March 1943.
