Just added to the shop. Two super-sized enamel pins for the Space Shuttle and for Apollo featuring the Lunar Roving Vehicle. Both are a HUGE 4" (that is big for an enamel pin), but not as heavy as you would expect. The manufacturer compensated with a thinner metal and lighter weight. 

Then we will also toss in a special 1.75" pin for the ISS for free. 

Quarter not included. ;)
