I've changed many times my way of collecting.
When I began, I only tried to collect animal toys I dreamed about when I was young: 1/32 scale plastic models from the 50's to the 70's.
On this path, I felt on older hollowcast lead and composition toys, so I enlarged my collection range.
Then I just couldn't resist to some "accurate" modern dinosaur toys and I enlarged again my realm.
My guidelines then was no modern style wild animals, no farm life, no sea life, no horses, no pets and no resin or handmade models.
I broke my vaults several time and I collect for years now Modern sea life, wildlife toys and of course Resin and homemade models from my STS friends
My collection grew up and decreased several time and I even thought to put a final point on my collector's life last year.
Economy and personal behaviors decided me to reduce my collection again and to save money for buying more 3D or handmade models
