This is an extraordinary one of a kind autographed poster of Santa Claus that was drawn in late 1961. It's signed by the Mercury 7 and the New Nine group of astronauts, plus Shorty Powers, who was the PAO and voice of the Mercury mission control .
The artist is Grant Lathe, who was a NASA graphic artist from 1960-1986 and I bought his entire collection of artwork, vintage signed photos, concept drawings, NASA books and materials from his family at the 2006 San Antonio UACC show.
This poster is hand drawn by Grant, I'm assuming that he came up with the caption while listening to the Mercury astronauts talk about how to safely orbit the earth.
This is one of my favorite pieces in my collection and it's a unique piece of space history.
