Sign IIIC-2: “route board”. Based on reference drawing in Instrukcja o znakach i sygnałach na drogach (English translation: Instruction about traffic signs and signals), made by Ministry of Communication and released in Warsaw in 1975 by Wydawnictwa Komunikacji i Łączności.
Example of showing distances to multiple cities located on concurrency of two international roads in Poland. It is also worth noticing that the final destination and the distance are written in larger font – this feature appeared on kilometre signs in Poland practically until the beginning of the 2000s.
