This is a little booklet that was once full of hotel coupons; there is one left. It was issued to a Louis H. Knapp. There isn't enough information in this booklet to determine which Louis H. Knapp stayed in the hotel in Norway. I haven't been able to find any other information connecting Norway to this fellow.
Hopefully there is a Knapp descendant who can solve the mystery of which Louis H. Knapp this keepsake belonged to.
