This photo was taken September 1990 in Flagstaff, Arizona during a chance meeting between Doug Hollis and myself with Clyde Tombaugh and his wife Patricia. They happened to be visiting the observatory, from which he discovered the ninth planet Pluto, to make their first stroll together down the newly constructed Pluto Walk. The photo was shared with Clyde and received his signature in May 1992.
Congratulations Clyde Tombaugh on your historic visit to Pluto!

Thanks to Joe who introduced his six-year-old brother to meteoritics when he revealed the "impact pit" in the backyard, complete with a melted, bubbly "meteorite" (slag) at the bottom.
