The lunch box I carried to school in the early 50s was just a plain light green box and the thermos had a cork instead of a screw on cap. My Mom carried that same lunch box to grammar school in the early 30s.
My hero was Hopalong Cassidy. I loved how he was dressed in Black with his White horse. Most of all one of the things I also really liked was the shape of his hat. I still love the more traditional style cowboys. I carried his lunch box till fifth grade or so.
I remember having G.I.Joe, Dukes of Hazzard, and I think, Knight Rider. Dang, now I want to go to my parents house and see if I can find them. Just what I needed, more nostalgia. hehe
