American Graphics Poster ☜ 

I don’t often dedicate a post to a single image, but this fantastic poster for American Graphics Co. felt like a worthy exception. I haven’t been able to find much about this Chicago-based company, but I suspect they were an ad agency or design firm based on the poster’s copy. There’s still a business called American Graphics & Signs, Inc. that could be a descendant. No designer or date is listed, but I’d guess this was created in-house in the early 1970s. Whoever drew this clearly understood the joy of a good brainstorming session!
