Compare it to this douchey Y&R self-promo ad from 2006, and this idiotic Y&R self-promo ad from 1941.
Anyway, guys (or gals) at a sporting event or Beatles concert or air show might've YELLED it. Also, in the 80s, Crazy Eddie shit all over your theory, Y&R. But for the 60s, it's an OK ad, I guess. I still prefer David Ogilvy's 1,909 word monstrosity. Then, you have these eight terrible self-promo ads by today's agencies.
