A few fragments still exist, mostly at the retail level, that still use this livery. The Main offices were at the locations I mentioned, but the HQ was in downtown Pittsburgh, and the Research Labs where I worked in Harmarville, PA, right where the PA Turnpike crosses the Allegheny River. Madame Reclus is from Springdale (ancestral home of Rachel Carson), just up the river.

I worked there from late '78 to late '83, as a Senior Technical Analyst--the first three years in computer mapping of geological datasets and wellogs on an IBM mainframe, the last two as an image processing specialist on an HP minicomputer in the Remote Sensing Lab.

Now, two questions 4 U:

Why are you curious?
