Drawing on the WallEdit
The man pictured on the wall is a Guardia Civil, a member of the Spanish gendarmerie. he is wearing the traditional uniform with the shirt and the traditional hat known as Tricornio.
The Guardia Civil was founded in 1844, and it had military status which still maintains today. Due to the use of Spanish locations, and on a hypothetical 1940-1950 time lapse, they should be the police force in charge of supervision of the regular citizens and controlling burglary, just below the army in the chain of command.
