The other Who stub clearly shows the name of the band and makes identification of the first stub easy. 2 Ringo Starr stubs from 1989 Pine Knob MI.
2 David Bowie stubs from 1987 Rosemont IL. 2 Elton John stubs from 1998 Milwaukee WI and 1 Barbarians stub (featuring Ron Wood and Keith Richards) from 1979 Detroit MI. The best of these concerts, for me, was the 1978 Stones at Soldier Field. I was 19 years old and in Chicago.
The best seats were surprisingly behind the stage at the Elton John concert in Milwaukee. My wife and I were so close to the stage we could see Elton's hands reflected in the mirror on his piano. When put on display, these concert ticket stubs are a great conversation piece.
