I checked the copyright dates on my MB game boxes. They read copyright 1968 both on the inside (beneath rules print) and outside (side) of the top covers. It is interesting that I have one game box cover which does not read "Patent Applied For" on the outside side. I would think that they would all be exactly the same. I can only assume the printing of (or lack of) the patent text varied between production runs. Thanks for prompting me to check them out Carlton.
Love the MBs!
