Today in Comics History, July 6: Say, John Byrne...what day does the Calgary Stampede start?

...could it be on July 3?:



from Iron Fist (1975 series) #8 (Marvel, October 1976), script by Chris Claremont, pencils by John Byrne, inks by Dan Adkins, colors by Bonnie Wilford, letters by Joe Rosen
Well, maybe, but that was in 1976. In 1979 it's today!



from [Uncanny] X-Men (1963 series) #121 (Marvel, May 1979), co-plot and script by Chris Claremont, co-plot and pencils by John Byrne, inks by Terry Austin, colors by Glynis Oliver, letters by John Costanza
Now, John Byrne, you surely didn't pick July 6 because it's your birthday, didja?
