[PRCo] 1947 ERA HEADLIGHTS

[Mark McGuire]

  Hello all! 

  I was recently looking at the back cover of the July, 1952 ELECTRIC
RAILROADS(PGH interurbans).and I noticed that on the bottom right it
states that the July, 1947 issue of ERA HEADLIGHTS has a track map
of the interurban division of PRCo. I have a nice collection of these
but mine only go back to Jan., 1948.(dog-gone it!). How would I go
about obtaining a copy of this track map? Would this be legal or a 
copyright infringement? I sure would love to see that track map if it's
worth looking at. Thanks in advance!
