Vintage 1940's Advertising Pepsi Cola Door Push Metal/ Double Dot 5 cents Sign

vintage door push

this is a rare door push

it is 10 1/4 x 2 3/4

for its age it is in very good shape.

from researching they only made the double dots until 1940

on the bottom is m 20-2

not sure what that means but to collector they may know
