I can't say for sure about the film. Was it like a documentary or actual movie because I googled it real quick to see what comes up, there are a few but this one a main one about collecting lol It's called "Tommy Tricker and the Stamp Traveller" came out in 1988. I have been thinking about sharing parts of my stamp collection on here. I'm actually waiting on 2 to come in the mail and I'll probably share it some then! If you follow me keep an eye out for it! :)
