|DICK HYMAN| appears to be Anzeigen Grotesk:

|MGM| is too small for an accurate ID, but Vitesse Sans Bold by Hoefler & Co. or Eurostile Heavy might work.

I think you're right about Eurostile - the "HIGH FIDELITY" at the bottom has the appearance of Eurostile condensed.

Thanks to you both...you're amazing. Eurostile worked well, thanks and the others were spot on. Super appreciated.
