Koetz T. 193 – machine slogan cancel used in 1931
The slogan reads (in French): “Buy the Michel Rodange stamps.” But in 1931 there weren’t any postage stamps to buy that commemorated the Luxembourg poet Michel Rodange (1827-1876)!
Could the “stamps” be the Michel Rodange poster stamps like the example below?
If so, were they sold at the post offices? And for how much? I’m clueless. Why in 1931 would Michel Rodange poster stamps justify a slogan cancel? Surely collectors in the Grand Duchy must know the answer!
