Aerial view of Vulcan Park
This is my vote for the best Vulcan postcard.  It shows Vulcan Park as it was originally built.  The gift shop was the red roofed building.  The waterfalls and cascades are prominent.  U.S. 31 is visible as it passes through a gap in Red Mountain.   Warwick Drive is visible at the upper right.  The white slashes just to the left of Vulcan's head are remaining bridge abutments of the Birmingham Mineral Railroad.  
The card was published by Moore News and printed by E.C.Kropp.
