A Flown X-15 Cover
Here is my current (late '04) "take lunch to work and sell off my dupes to afford this" project. This is Ellington-Zwisler #102, flown on the October 3, 1967 flight of the X-15-A2 to Mach 6.7 by the late Pete Knight. It features a William Numeroff airbrushed design. Ten, maybe thirteen of these were carried on the flight. See my album "From Muroc to the Millenium" for more information on this cover.
