Romeo y Julieta #40 Aguedo Herrera (Boxer).

A fragmented Cuban tobacco insert series issued with Romeo y Julieta cigars featuring primarily boxing subjects, printed as small real-photo cards (about 1?" x 2½") on thin paper stock with Spanish advertising backs. The set was released in multiple numbered series or print runs rather than a single unified checklist, and includes Cuban fighters alongside occasional international boxing stars. Distribution was tied to cigar packs and album collecting.
