I bought these from a guy who went to estate sales and he was liquidating his stuff I thought they were kind of unique but I really want to know more about them I finally figured out that the cathedral is a cathedral in Vienna but I don't know what the picture of a room is are these lithographs are they sketchings etchings are the signatures recognizable please help I would hate to think that these don't hold any value I really like them by the way these are a little smaller than 8x10 and frames are wood is that helps.
