The first is, I believe, Halloween 1977. Dad's the tall one in the back, my younger brother is the small fry, and I am proudly wearing my classic Batman costume care of Ben Cooper. The second picture is from January 1980 at my Grandmother's birthday. That's Grandma in the center, with my brother and I on either side. Notice, if you will, the cup in the bottom right corner of the shot -- yes, indeedy, that was my Spider-Man cup.
