Jordan K. Weisman
From Tardis Wiki, the free Doctor Who reference
Jordan K. Weisman was credited with creating the "cover concept" for The Iytean Menace. This presumably means he came up with the idea of using a cropped version of Gustave Caillebotte's 1877 painting Paris Street; Rainy Day as the front cover art. Caillebotte himself was duly credited for "cover art", with no clear disclaimer that this was actually a preexisting public-domain artpiece being repurposed.
