Intriguing Direct Mail -- But I Can't Figure Out How to Take Advantage of Your Offer

I received a brown kraft direct mail envelope promising "solve riddles and save on your next purchase of photography or type."   Inside, I was presented with 7 Offers -- each in the form of a Riddle I had to solve, just to take advantage of their Offers.

Unfortunately, I had no idea what the answer was to any of the 7 Riddles.  No phone number or web address appeared on the 7 Riddle pages.  So I tossed the mailer in frustration.  Why would such a creative package fall apart when it came to Offers?
