I used whatthefont.com to identify the font used in this logo and it told me that the font is most likely Engravers Gothic BT. When looking at this font you can see that C and O are almost perfectly circular. I like this font because it is simple; I feel like this is the font Marc Jacobs chose because it’s not showy. He doesn’t have to make his logo anything special because he’s Marc Jacobs. It’s like the name says enough. You see the name Marc Jacobs and you just know.
