For Throwback Thursday, here’s an advertisement printed on July 4, 1976, from the construction services companies that worked for Hersheypark during the the 1970s renovations. They were congratulating Hersheypark on its 70th anniversary. The construction services companies seen here are: H.B. Alexander & Son, Inc., Kimbob, Inc., G.R. Sponaugle & Sons, Inc., and John B. Minnich & Son, Inc. The map of the Park used in this advertisement was from 1973, and was printed in a special section celebrating the 70th Anniversary of Hersheypark in The Patriot-News on July 4, 1976.
