Last 45rpm edition on the 1961 blue label and with yet another back cover variation (different font).
In 1961 RCA Victor reissued all the Brazilian 50's EPs on 45rpm for a last time and right after reissued them on the new format, 33rpm, with simple sleeves (very fragile) and the new black Compact Double 33 label. The 33 format would be the standard for the Brazilian market from then onwards.
Labels mention: Fabricado pela RCA, S. Paulo
