When I was involved in finding the Donn Eisele Speedmaster from Apollo 7, the Smithsonian gifted me....... a coffee mug. Lol. Very nice of them, but kind of a funny gesture given the whole situation... Anyways, it's become my 'daily beater'.
I used to buy tea cups when I Went on holiday but after several of them broke before I even got home I swapped to fridge magnets. My wife is from Finland and all of our cups have moomins on them.
