My 1964 painted black haired, hard-hand 12" GIJOE, I believe to be an Action Sailor-bought for $25 in 1984/5-ish.
The second isn't a Joe-item---its an original edition 1/43 scale Corgi Batmobile.
And the third is the POC wave 3 Snake-eyes. Hands-down my favourite small GIJOE type toy figure. Period. Nothing beats it, and I imagine nothing ever will.
If I had to pick a Joe vehicle..........the Night Attack Copter, sure, its modern, but I think its the best aerial vehicle in the entire line--its just captures my imagination more than anything else they have done.
