Frostman's drawings on the glass

I carry my camera with me quite often when I visit my country home. Like this time I decided to take it with me, because I already carried it from tartu to Hiiumaa, so I didn't want to go back without any photos. I used my chance and photographed a glass. It sounds weird, why someome photograph a glass, but this time I had a reason. Frostman had left his prints on the glass and I used my chance and saved it all to a sd card.
