Inside one of Gene Krupa's drum hardware cases we found these random drum sticks and mallets. I have not seen photos of Gene playing the vibraphones, but of course we know his longtime bandmate Lionel Hampton could have easily given these to Gene. Either way these are well used and a cool piece of drumming history.
