Panini football stickers.
And Shoot magazine league ladders.
I was just curious if others were as sad. Haha
As a kid I used to collect Smarties Tubes - You'd be surprised the amount of different designs they had at one point.... Still do in fact, even if it is the Hexatube now.
I started collecting them for tokens because of a free giveaway they were doing in 1990/91 (one of several over the years) and realised eventually that I had managed to collect more than I needed, so I kept them, and it escalated from there. I even made a point of collecting foreign versions when on holiday (which were almost always White).
I ended up with about 40 or 50, some duplicates of each other, some collected specially for competitions, a change in design, some, special pieces of 'Artwork' on them (yes they did several versions and I never did get all of them), and so on, but the most prized ones were the individual examples such as the extended 'Fun box' from Southern Ireland that was about 6 inches long.
Anyway, after years of my Mum threatening to throw them out, I eventually donated them to The Museum Of Brands in London,
http://www.museumofbrands.com/ so hopefully they will become part of some sort of packaging national collection!
