September 20, 1938

Source:, lot CT146

Postcard to Valencia, franked with 25c Edifil 749 and 5c Barcelona local Edifil 19, Barcelona postmark dated on Sept 28, 1938. Addressed to Arturo González del Río. The sender is his brother Julio.

The back of the post card contains a printed space for the sender’s info: “REMITENTE: / PREVENTORIO: J / OFICINA DE CORRESPONDENCIA / Muntaner, 55 (bajos) BARCELONA”.

This is the only example we know of this kind of post cards for prisoners printed by the SIM. We have seen several examples where prisoners in labor camps and preventories write themselves the Servicio de Información Militar (SIM) mail office address of Muntaner, 55 bajos, Barcelona, on their sender’s info, but this is the first time we see this stationery post card especially printed for prisoners.

Seen once in a lifetime piece. The rarest SIM & Republican labor camp and prisons system related piece we have ever seen.

Queridos todos: Recibí vuestra postal de 29 de Julio alegrándome de que todos estéis bien.

Estoy estupendamente de salud, trabajando de mecánico en un taller de reparación de automóviles y no nos falta nada, lo mismo en trato que en comida y estancia, de modo que podéis estar tranquilos.

Muchos abrazos a todos, especialmente a los viejos, de Julio

Dear all: I received your post card dated on July 29 and I am happy to learn you all are fine.

I have very good health, I am working as mechanic in a workshop repairing cars, and we do not lack anything in treatment, food and housing, so you don’t need to worry.

Lots of hugs to all, specially to the elders, from Julio
