Saddle-stitched paper songbook with a color-printed cover on a black ground (limited palette of black, blue, white, and red-orange). The cover cartoon shows a figure singing joyfully in a shower — showerhead raining drops, musical notes, soap bubbles, one arm flung up — holding an open copy of this same "Cantemos…" booklet, a recursive image that reprints the cover in miniature. The title "CANTEMOS…" runs across the top in white; a circular "20¢" price roundel sits at upper left; the lower zone carries the Radio Progreso logo (a stylized rainbow-striped "P") with "RADIO PROGRESO" and the slogan "la onda de la alegría." Signed "FiG/79" at lower center. Interior not shown.
