It's three fonts.

The magenta one is ITC American Typewriter.

The purple one is VAG Rounded Bold

and the yellow one looks like Rockwell

The American Typewriter doesn't match, bottom right.

perhaps modified - I cannot think of another C with that top!

A designers trick? American Typewriter mixed with AG Book rounded?

Thank you at all, I had already tried american typewriter .. :-)
i go to redraw this "C"

A doddle, mask and cut cyan green and yellow, grayscale, adjust the levels, trace, clean and ... Bingo!
