The inmates of labor camp numer 5 came from the prison ships Argentina, Uruguay and Villa de Madrid, and also from Valencia and Madrid prisons, from Figueres prison, from Tarragona prison, and from Model, Montjuïc Castle and Pueblo Español, these last three in Barcelona. The camp was operative from July 2 to November 18, 1938, when all prisoners were moved to Barcelona's Seminary, then the S.I.M.'s Preventorio C (prison).
The post card is undated, the postmark is unreadable and there is a stamp lacking.
