Last year, I posted the 50th Anniversary Opening Day lineups for the National League and American League teams from 1966.
I was going to do the same for the 50th anniversary of the 1967 teams, but realized that I had already done that back on Opening Day in 2014. So I will just re-post those links for that season (my 1st following major-league baseball), and will remember not to get ahead of myself for '68, '69, or '70.
Starting pitchers for all 20 teams
