No bomb imagery, please - this is the wrong way to go!
Please see my Pinterest album with selected designs from (or in the style of) 1960s graphics and logos. I would like to evoke some of the qualities of the top graphic designers of the era, e.g. Saul Bass, Milton Glaser, Peter Max, and come up with something that is witty but to the point - combining the concept of "reinvention" with the memories that boomers will have of their youth, and the graphics, colors, shapes & patterns that were cool at that time.
Having said all that, i don't want to make it too "period" and without reference to today's design world. Tall order, I know, but I'd like to try to have some degree of synthesis between today and yesterday. For my customers, the message is all about how to be successful in Today's world, vs. bemoaning the way things used to be.
