This rare lunchbox made by King-Seeley Thermos Co.,Thermos Division was up for auction on eBay and finally sold for $1036 with a total of 23 bids. This is super rare and only a few were made. The seller wrote:

I received this as a child from my mother,who bought it that day at a yard sale (in the early 80's).At that time the zipper was messed up & the top looked to had been mashed (witch left a couple of dents in the top (dome),& the piece of vinyl hinge was worn a bit.My mother wrote my name and phone no. inside the top.As the years past I must have put two decals on the top (i can't recall if i put the decals on or if it was like that when i got it).
