Shower shoes worn by Ken Griffey Jr show nice use, with each having his number 24 written in fading black marker. Rubberized Raves slippers are marked size L underneath. Unusual memento from the man whose 630 career round trippers ranks 7th on MLB's all-time list, earning him induction into the Baseball Hall of Fame on his first ballot in 2016, amassing over 99 percent of votes cast.
