This is the beautiful Darrell Waltrip Western Auto Kenworth Aerodyne Transporter.  

It is from the Matchbox NASCAR Super Stars Collection. This was released almost 20+ years ago, in 1992. It is a great cross-collectible, so if you collect Matchbox, Kenworth, Western Auto, DW, or NASCAR this will be a wonderful addition to your collection. (1:64 Scale)
