Maker: John Heap - ±1913
The The Strong National Museum of Play of Rochester, N.Y. gives the following explanation of this game:
"The Heap game was an important piece of evidence in a Monopoly copyright dispute that began in 1974 and spanned a decade.
John Heap was a civil engineer working for the Pennsylvania Railroad in Altoona. Museum guests can see that Heap’s board reflects his careful design and skills as an engineer and it represents his home town of Altoona, with still-existing streets marked in pen, and postcards showing local landmarks."
