My recent Ebay purchases include two items in particular:
1 - A commemorative polo shirt issued on the occasion of the opening of the "Jean Shepherd Community Center" in Hammond, Indiana. Finally Jean Shepherd was honored in his home town. I thought this was a unique Shepherd artifact related for my collection (which really only includes records of his old radio shows and a few books).
2 - This HO scale (1/87) model kit:
As a kid, I built a model just like this (it's probably still around somewhere) for my model train layout. There are still very few models of modern-looking homes like this, which was manufactured in the 60's. With the skills (and patience) I have now, I'll super-detail this new home with the tiny details and lighting that make it seem authentic. I'm in the very early stages of developing another layout, for which I've purchased a number of structure kids already (I'm finishing work on the first of them now). More on that later.
