Umm, i own Australia's largest 1970/1980's BMX museum 
I have 200+ bikes & 1000's parts/clothing/stickers, being an ex champ myself ('83).

Besides BMX, i collect my old childhood toys, cereal toys, Mad Magazines, Soldiers, CB Radio's, and ship loads too much more....

It's almost time to cash in on most of it and buy a house or 2.....or a lotta pins ;-)

PS. i used to make fantasy swords....small world.
