The 1970's continued photo map covers except for the attractive 1976 Bicentennial cover.

	1970
	1971
	1971 Penna Turnpike, Pennsylvania Turnpike Commission. This 11 x 17 inch brochure has a Rand McNally map dated 1971.
	1972 Again, a truly awful photo and cover design.
	1972 Penna Turnpike "The Bicentennial Highway", Pennsylvania Turnpike Commission. Dispite what is on the cover, this 16 x 18 inch brochure has a Rand McNally map dated 1972 . It is more detailed than the previous ones and similar to a commercial Rand McNally state map.
	1973
	1973 Penna Turnpike The Bicentennial Highway, Pennsylvania Turnpike Commission. This brochure is very like the previous one except the Rand McNally map is dated 1973.
	1974
	1974 A second 1974 map was issued titled 'Fishing and Boating Map Special Issue'.
	1974 Pennsylvania Turnpike, Pennsylvania Turnpike Commission. This undated brochure was put out during the Shapp years and so is dated 1974 here as no other turnpike item for that year has been seen. There is no map inside, just some colored lines to figuratively represent the pike.
	1975 This is a picture of Independence Hall in Philadelphia; finally, no concrete.
	1975 There's nothing like the Pennsylvania Turnpike, Pennsylvania Turnpike Commission. This 12 x 16 inch brochure has an uncredited Rand McNally map that is code dated to 1975.
	1976 The state managed to get a really good cover design for the Bicentennial. This map also has a larger folded size, about 9 x 5 inches, instead of 9 x 3 inches.
	1976 There's nothing like the Pennsylvania Turnpike, Pennsylvania Turnpike Commission. This is the actual bicentennial map expanded to an 18 x 23 inch size. It has a larger (and credited) Rand McNally map dated to 1976, and surrounded with small maps of the interchanges.
	1977 Apparently Pittsburgh complained about all the Philadelphia related covers lately.
	1977 Penna Turnpike, Pennsylvania Turnpike Commission. This 12 x 18 inch brochure is a redesign and now has a dated General Drafting map.
	1978
	1978 Penna Turnpike, Pennsylvania Turnpike Commission. This brochure is similar to the 1977 one except for the cover picture, and is believed to be a 1978 issue.
	1979 No official map issued; the state began issuing official maps every two years. Shown here is a Pennsylvania Turnpike Commission map. This brochure is identical to the 1978 one except Richard Thornburg (1979-87) is now listed as governor, and so this is a 1979 issue.
