This is the Index of Happiness Tote, designed by artist Donald Baechler and accessory designers Richard Lambertson and John Truex.

The tote, available only to American Express cardmembers (call 1-866-558-3072), takes a classic Lambertson Truex design and adds original artwork, one of this season's most delightful and exciting accessory trends.

This artwork from Donald Baechler goes to benefit the art of others; 15% of the purchase price of each bag will be donated to the Whitney Museum of American Art's Photography Program, Collection, and Special Exhibitions.

The bag is suede, trimmed in Italian leather, and accented with plaids that complement Baechler's work. The inside of the bag features a blue leather patch signed by all three design contributors personally, as well as additional artwork by Baechler. The bag can be yours for an even $1,000.
