LuMarc Bold comes very close:

Some of the tails aren't quite right but that is the closest I've been able to find!

I agree with Kevin that LuMarc Bold is close, but despite the small scale of the image [can we get a larger one?] there seem to be differences. Here is Lu Marc Bold

This is another size I found of this.

Also trying to identify this 50 as well.

1. How about TFArrow Extra Bold

2. ifty Years: Bickham Script
Adobe Systems/Bickham Script 400 Italic

Dick, I think you've got it.

was worried that both might be derivative.

I have already found the Fifty Years. I am looking for the 50

Both of those are dead matches. Just can't find the 50.

The numerals resemble Caslon (old style figures), but not quite. I'll need to isolate the numbers and run a search.

You are amazing thank you!

Big Caslon, but someone substituted a lowercase o (and widened it) for the old-style figures zero:

Big Caslon Medium comes bundled with the Mac operating system....

Dick, congratulations on another bullseye! BTW for anyone not familiar with Treacy Faces, they were among the best from the first wave of digital fonts. They show a lot of effort to make the contours precise and effective and hold up very well in competition with more recent fonts.

Thanks for all of your help!

Once again, the solve should go to Dick Pape....
