I’ll admit this Penthouse t-shirt is far from the most exciting thing I’ve ever seen. Just more corporate advertising. But seeing as how the model wearing the shirt is Penthouse Pet Heather Vandeven, well, that’s something else entirely. Heather was voted Penthouse Pet of the Year 2007, as well as Pet of the Month January 2006 – and rightly so. These photos of Heather and her shirt are from a recent signing. Now if only that t-shirt were wet! Four mine fine pictures of Heather after the jump.
