This is a test run for our monthly contest that will run throughout 2011, but the prizes are 100% real!
Just as we will each month next year, we are giving away a crisp, new copy of our book, American Genius: Bank Locks and Time Lock of the Nineteenth Century. Reviewed by the Wall Street Journal noting that bank security “never looked so good,” American Genius offers one of the most thorough and beautiful looks at the art and science of time locks and other elements of early bank security. Packed with new analysis of original source documents, American Genius is a must-own for anyone who takes an interest in safes, locks, vaults or American industrial history.
Above is a portion of a time lock patent. We will give away one copy to the first person to send us an email via our contact page that correctly identifies the time lock from whose patent this image is take. We will give a second copy to one other entrant drawn at random from all other correct entries.
For full details, please see our Contest Guidelines — but remember: it’s all free! After all, we think the world is risky enough as it is these days.
