The detail at left is from a picture book I treasured when I was a kid. (Well, not just when I was a kid. It's still pretty great.)
Take a good look, then tell me some of the things you'd expect to find in the illustration on the book's LAST page. You can guess as many as you want; I'll acknowledge whoever gets the most.
Possible answers include (but are probably not limited to) two ungulates, a dirigible, a metal fastener, a musical instrument, a flower, several countries (current and former), a member of an African tribe, a menagerie, something with twelve parts, a masked man, a Greek philosopher, and (I think?) an American writer.
NOTE: If you own this book, no cheating! You can still play... you just have to do it from memory and your own wits.
Hint
A citrus fruit is mentioned five times in the article's text.
The full Wikipedia article is quite long and full of choice quotations.
(By the way, the hint was a reference to "lemons", another name for defective or inferior cars. But it led one of you to guess that the article was called "List of automobiles known for being orange", which made my day.)
Solution
These cars are known for negative reception, for a variety of reasons. The Edsel was a famous flop (sorry, I mean a no-go). The Trabi and Yugo were low-quality cars from East Germany and Yugoslavia that became emblematic of Communist market failures. But the unsafe Corvair and Pinto arguably said worse things about capitalism—the latter was knowingly released by Ford with a design flaw that could cause it to catch fire in collisions! The Hummer, the only car mentioned in the puzzle that was produced within any Proofnik's lifetime, was criticized for looking like a tank—and having about the same fuel efficiency.
Congratulations to yesterday's solvers Charlie, Jacob C., Inca, Leo S., and the Greggs. Thanks to everybody who made a guess!
Ten years later, Dr. Shapiro revived Puzzle of the Day at Proof School, writing each day's puzzle on a name tag. After 600 puzzles or so, he was just starting to feel normal about students reading his chest all the time when campus closed and the puzzle, like the rest of our lives, moved online. New puzzles are posted daily on school days.
