I saw this font and love it.  I'm assuming it is an art deco font.  I've been searching the net for this font on this wiki page, on the image of Keller letterhead that says Keller motors cooperation.  I can not find out what it is.  please help.  https://en.m.wikipedia.org/wiki/Keller_(automobile)

You might find something close here among these Deco typestyles that you can use instead:
