4 Republican & Democratic National Convention programs 1960-1968

Group of 4 programs from the Republican National Conventions in 1960, 1964 and 1968, and from the 1964 Democratic National Convention.  Two are 9 x 12", and two are 9 1/2 x 13".  The 1960 RNC program shows a little wear from use on the cover - the others are in generally excellent condition.
