Questions regarding street corner name signs of the 1950's

[Detroit Signal]

Just for reference, I have all three generations of the most recent signs. The white and black signs are significantly shorter than the newer green signs.

The only thing the older green sign's missing is that block number on the upper right corner.

There were three versions of the green signs.

The one you see without the block number [[that's older than the current green signs) was the 2nd version.

You might say there have been four versions of the green signs: FHWA Series C, no border, no number; FHWA Series C, no border, with number; Clearview 1-W, white border, wide-spaced; Clearview 2-W, white border, narrow-spaced [[the current issue). http://www.terminaldesign.com/fonts/...mplete-family/

When were the green signs with the block number in use? There was one still up at Eastern and Chope in July 2009 when the Google car drove by.

That actually reminds me-earlier this month while I was doing something entirely different I accidentally stumbled upon a green sign [[the one that was used before the ones with the block numbers) on the I-75 service drive just southwest off of Fort Street next to the Fleetwood container site that was still up as of four months ago. Here's a closeup taken in September 2013.
