In 1988, the Oscar Mayer company offered this promotional item. It can still be found occasionally on auction sites. This pan flute is not the only wiener whistle that the company offered, but appears to be the only one capable of multiple tones. The back side of the label provides instructions for playing the enchanted tones of the company jingle.
This pan flute is certainly superior to the alternatives, as it offers a loop at one end so that the instrument can be hung around the neck with a lanyard or at the waist with a retracting belt reel. Always keep your wiener whistle handy for emergencies.
