Dolphin mailbox and other mailboxes in Mailbox Picture Collection

I always like to look at the Sam's Mailbox Picture Collection http://sblom.com/mailbox/

This collection has very funny novelty mailboxes, for example unusual dolphin mailbox, whale mailbox, train mailbox, golf mailbox, airplane mailbox, flamingo mailbox, motorcycle mailbox and so on. Some of these mailboxes people can buy, for example at http://mailbox-plaza.com/. But some of these mailboxes apparently were made by the owners.

Novelty Mailboxes that relate to small businesses

I can see often that small businesses like to use a mailbox that relates to the business. For example a small airport uses Airplane Mailbox as their mailbox. Golf course uses Golf Ball Mailbox or Golf Bag Mailbox. On Hawaii whale watch or dolphin watch businesses use Whale Mailbox or Dolphin Mailbox. But I never saw a fire station that use Fire Engine Mailbox. Apparently fire stations don't like fun
