Have you Met Bill Jones? 1930's Motivational Cards Propaganda Parker Holladay Co.

Have you Met Bill Jones?
An almost complete set of 1930's Motivational Propaganda cards by the Parker Holladay co.
I have had a larger version of these cards awhile ago and now I have the luck of coming across another set These are a bit different, they are Black and White and are made by the English branch of the Parker Holladay co.
The original set of cards were made in the 1920's by the American Co. Parker and Holladay Chicago.
Originally made in a 1920’s propaganda campaign used to motivate people in the work place. Displayed in work areas to promote industrial efficiency and unify the work force, they were made to show what a model worker was. The original designer of the cards was by a man named Charles Rosenfeld who was a sales man for The Mather Co. in Chicago.
In this set I have 22 and the highest number is 24. I am not sure how many were in this Black and White set, but the original set had 52 for the weeks in a year.
Please note I will adding another set, but these are in Color and are a full set.
