This card shows the from of the barracks building that served as the base headquarters.
There is no description on the back of this card. There appears to be a perspective error on the part of the artist who colored the photo, as there is an inexplicably large cannon barrel behind the shrubs on the left, while there is no matching piece on the right, as would be expected.
The card does not have any distinguishing datable features, but the person who purchased it would have acquired it in the late 1960s. The card is of a type produced in the 1950s.
