Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

 The changing look of Umbrella Man and his pal.

So, above, the pal is all in white and is wearing a black French beret and Umbrella Man has a light shirt. Bottom right, the pal's jacket is green, and he has a high-top, flathead haircut with no hat. Umbrella Man's shirt is dark.  Bottom left is Bronson, and now, Umbrella Man is wearing a hat, and his friend's jacket was light blue and white. Harold Wiesman thought the Bronson images were fake.
