The term 'mib' comes from the old marble-playing days and is an acronym from the words 'Marble In Battle'. Over time the word mib simply came to refer to any kind of marble, and these days we even use it sometimes to refer to art glass marbles. This marble features Zach's murine/milli image of a group of playground marbles, and then several other larger individual marbles are seen around the marble. Yes, what we have here is mibs on a mib!!
