I used to collect rocks, cards from bubble gum packets, coins, stamps, tractor pamphlets ( used to write away for them... I had a sales rep turn up one day hoping to sell a squillion dollars worth of earth moving equipment
... I would've been 8 I think...), motorcycle pamphlets and manuals, stickers, and then as I got older I started collecting tools, motorbikes, telescopes... toys in general
