Pawnshop

We came across really interesting business model through coolhunting.com post.

a pawnshop is a short-term loan business, which retains a collateral object (artwork) in exchange for cash -- a small fraction of the object's (artwork's) value that must be repaid with interest for the item is to be re-claimed by its original owner. If, after 30 days, the item (artwork) has not been claimed, the pawnbroker earns the right to sell it, and the pawned object remains on display until it is picked up or purchased by someone else.

Taking old ideas with negative association and turning into something more desirable. How about that for innovative business model?
