Several years ago I came across a selection of various toy prototypes from a former employee, among this lot were some G.I. Joe pieces. Mainly accessories, some of which I have identified - but I'm not particularly aware if there may be something especially interesting in there or not.
There were also some sample camo face paints included:
One of the pieces that I could readily identify from being different to production was this:
with a clear visor.
Here are some more pictures of the lot:
Not great pictures I know, and obviously some items are not Joe but any help would be appreciated.
The little rubber ninja guys are ticket wins at various pizza chains. I have some purple and black ones from a pizza inn back in 1990. Also, I think the silver order is a custom, if you look closely you can see where the paint has pooled in some of the sculpt. Oh, and aerosol can is a small micro machines playset. There is a way to take it apart, but some of them can be a bit puzzling to figure out. I had a blue one and it was annoying to unfold and put back together!
