What's the Difference?

by George Barany

This easy puzzle (11x17) was written in homage to this historic puzzle, published in the New York Times, and was inspired (spoiler) by this article in the Philadelphia Enquirer. Note that, within experimental error, my age (58) is the arithmetic mean of the ages of 51-Across (left photo) and 19-Across (right photo). Update November 24, 2014: Reposted today, on an auspicious occasion in the life of one of its honorees. Furthermore, please go to the 14:00 point of this video to hear Will Shortz discuss (for about 3 1/2 min) the original historic puzzle and its co-constructors. Update February 2015: Time to take a final, loving look at this puzzle. After solving (spoiler), please read this, this, this, this, this, and, most poignantly, this.
