#40

According to keycollectorcomics.com:

* Scarce promotional edition obtained by submitting three Frigo Cheese Heads UPC bar codes to Saputo Cheese. * 5,000 first prize winners were to receive a copy of Ultimate Spider-Man #40 (Not For Resale in low left-hand corner).

This variant shares the same indicia, page count, and advertisements as the standard edition, which suggests that they were printed at the same time.
