TT Scale. The Ideal Scale.

Guys, I need your advice.
Yesterday I purchased one more International truck. It was a van.



(For unknown reason it was marked as ZiS-150, but we know the truth! )

I want to put some logo on the van; I think it must be the transportation/logistic company logo (am I right?)
Something like this one:

I have a color printer and a special paper for decal making, so I can print any decal.

So, can you advise me any logo/emblem, suitable for 1950s ?
