The date on this Chicago Coin pinball poster is unknown to me, but was probably made before 1977 when its assets were sold to Gary and Sam Stern, forming Stern Electronics and then Stern Pinball.
I can’t look at this poster without thinking of the classic Sesame Street’s pinball animation to help kids with numbers.
The International Arcade Museum has quite a list of the games Chicago Coin made.
Pinside has a shorter list, but with images!

The poster copy:
Watch out for Chicago Coin.
We’re going to be the biggest thing in pinball.
