These three cards are part of the CANADIAN LAKE SUPERIOR POST CARD SERIES. They also have the NOR-WEST-MOTEL on Why.17, N.W. Schreiber, Ontario printed in the left top corner. They had a newspaper cutout of the motel attached, which is included in this lot.  The cards were purchased on the family's trip in the early 1960s.
