Lycoming Piasecki Work Horse Helicopter 1953 Advert

This is an original U.S. advertisement (not a reproduction) carefully cut from a magazine of the period.  It is about A4 size (approx 12 inches by 8 inches), and is well printed on a decent quality semi-gloss paper. This is a fascinating piece of aviation history.   There is a light vertical ridge down the page centreline, but it is in good condition and would make a great framed item or collector's piece.
