February Sign of the Month- 1920 Harley-Davidson WJ Sport Twin Gas Tank

This Harley-Davidson 1920 WJ Sport Twin, with its' 37 Cubic inch air cooled horizontally opposed twin cylinder engine, looks great in its' green livery.  The lettering on the tank is superb.  Introduced in 1919, it was in production until 1923, when it was discontinued due to poor sales. Next month's Sign of the Month will continue with an early example from H-D's biggest rival.  To me, a gas tank is rolling advertising, a mobile sign if you like.  This bike can be seen at the Trev Deeley Museum in Vancouver, B.C.
