Danish Bathing Machines

This postcard is from Denmark.  My parents lived in Copenhagen in the late 1950's.  As a kid I loved this postcard.  Mom told me that the horses pulled these machines into the water while people were inside changing into their swimsuits.  Then you were able to get directly into the water.  It was more discreet I guess,  I don't know why my brother's name is written on the card.  Maybe he was the one who wanted to buy it in the first place,
