Collection of Keys

Since my logo is a key "The KEY to your decorating needs" I've decided to start collecting old keys. I usually rebel against any kind of collection. Don't know why but maybe it's because most things that are a collection gather dust and look cluttered. However, I figured if I collect big keys they will make a statement. I'm sure I'll find more at thrift stores, garage sales, etc. I especially love the old antique keys but would love to find some really modern ones too.
