I recently made a rare for me, eBay purchase, a Lionel GP 20, 6-8563 Missouri Pacific diesel. It was packed with Styrofoam peanuts and the engine was wrapped in a new red " Wanta Pizza?", Pizza shop promotional tee shirt. I was happy it was wrapped in something to keep those Styrofoam peanuts from sticking to the paint job.
We call "a that little extra" , Lagniappe in Cajun country. I have used that red tee shirt dozen or so times working in the yard, around the house, etc. Many more times than I have run that GP 20 so far.
