'Super Bowl XL Opus' — At $40,000 it's the world's most expensive new sports book

It's also the biggest, measuring 24"W x 24"L x 5.5"D and weighing in at 90 pounds.

The 950-page coffee-table-size limited-edition book (above), which comes in a silk-encased box, is signed by every living Super Bowl M.V.P.

How do you spell "collectible?"

Not up to spending $40,000 for a book?

Can you go $4,000?

That'll get you the very same book, minus the autographs but containing all 2,000 pictures, many never before published.

Interestingly, when Richard Sandomir wrote about the book back on January 17 of this year, each signed copy was projected to cost $25,000.

Stuff happens.
