Nice stamp with full Olaa town name in Red. 

 

This rare postmark had very limited usage

from July 1894 until January 1898.

 

Meyer Harris # 281.9a13 and it is estimated 

that there are less than 150 known examples 

(in four possible colors: purple, green, black, and red).

If the four colors were equally distributed 

that would be less than 38 of each color. 

However, this is the only red example that I've seen.
