Over time, people get all sorts of manic interests...that manifest themselves as 'collections'.
Snowman, for eg has 'every' skin ever made....for any proggy.....
My interests are diverse....so there's more than one thing I like to collect.
It gets a bit crowded when you have 16+ bicycles........I'm attempting to rationalize that.... so currently, including frames there are....er.... 21.
When I was five I got into Meccano ....so 48 years later I still have that No. 3 set ....plus the equivalent of beyond a '10'..... 7 or 8 boxes of the stuff.
Motor Racing Officiating....over 30 years..... I try to limit myself just to caps for the World Superbikes [they're particularly well embroidered....FIM badges, etc..... I end up with 4 or 5 others each year....so the F1 and Moto are passed on to other 'fans'.... but then there's service badges...pins....programs....posters....tabbards....and pieces of car/bike.....
When I was 10 it was Magnus the Robot Fighter [comic - Gold Key] .....I wish I'd kept them all back then.....they're worth money now....but I have 'most'.
When I was 5 - 6 I had all 72 [I think] Matchbox cars...as on the typical display case .... and I sure wish I'd kept those.... could just about retire now...
Anyway.....what monopolizes your collective juices?
What do you collect?
