All About Pocket Knives

I have this old knife board with the date 1961 on it. It looks like they sold for $1.29 or $1.39. It is for Imperial jackmanster knives. The knives are makred USA only but the secondary blades do have the pat. numbers on them like most Imperial knives. Can anyone tell me if these are the corrct knives for the board

I can't date that card specifically, but the graphics are consistent for Imperial in that time frame.

Here is one with similar graphics from 1963, courtesy of Larry Vickery at http://www.collectors-of-schrades-r.us/
Notice specifically the crown logo.
