When the postal services used to be privy to royal or lordly power, CONVENTS, universities or merchant corporations, there was no need to announce the point of departure of messengers. But after this precious service was open to common people, and particularly in large communities, it was essential to indicate its location.
Thus the Postal Signposts appeared, in order to indicate the contact points of the postal service to a crescent public.
This "Directory of Post" Signpost is made of iron and painted on a blue background. It has a rectangular shape and the top is ornamented and decorated with golden elements. It also has a hook for hanging in the walls. As the center element, it has the Royal Coat of Arms painted in shades of red and yellow, with small blue and white notes. Immediately below the Coat of Arms there is written in black, over the design of a semi-circular white scroll; "MAIL DIRECTORY".
