BILL - That's IT....the very sign. That must be a really old pic, I'd say early 60's? The whole frt office entrance was remodeled but I don't know when for sure, but I was down there between Thanksgiving & Christmas and you can still see the bolts that were cut to get it down.
In looking at that pic closer, I actually think the pic is of the WEST entrance, was the HR entrance. It had steps, the EAST entrance was ground level, no steps. So pic may be older, late 50's? And the sign must have been moved to the east entrance when the offices were expanded towards the east. Materials and General management was on the ground floor of the east side offices, accounting, forcasting, purchasing, & scheduling. Engineering was on the second floor.
There was an employe's entrance on the south towards the parking lot. Just about ALL salaried people went in that way.
