coloring books

the 1960s gave us some great things. Astroturf. Twister. the ATM machine. but I don't think they will make you snigger as much as this, The Executive's Coloring Book, from 1961. Genius. I think my favourite line (though there are many choice phrases to choose from) is:
"Executives are important. They go to important offices and do important things. Color my underwear important."
