John Marzano H&B pro-model ("M110") baseball bat, dating from the 1986-89 manufacturing period, signed in black marker on the barrel by the following eight former United States astronauts: Scott Carpenter (Mercury Seven), John Glenn (Mercury Seven; first American to orbit the earth), Gordon Cooper (Mercury Seven), Charlie Duke (Apollo 16; youngest man to walk on the moon), Tom Stafford (Apollo 10), Gene Cernan (Apollo 17), John Harrington (first Native American in space), and Mae Jemison (first African American woman in space). While we have seen many items signed by several astronauts, bats are exceedingly rare and we cannot recall the last time we have seen another at auction. Signatures average 9/10. The bat shows no use and remains in Near Mint condition. Full LOA from JSA.
