Garfield the Movie Metal Lunch box

I got this as a give away about 10 years ago in England. It is clearly a tie in to Garfield the Movie but a search of Ebay and other places does not turn up anything like it, so I am unsure of anything else about it. I am perplexed why it is not turning up on any searches anywhere. It is metal, and I do not know if there is a thermos since it is in the original wrapper never opened - but I suspect there is no thermos based on weight! Has anyone else ever seen anything like it? Thanks!
