I need the font of the word "Pepsi-Cola." I have to remake a retro poster as an assignment for my classs and I need the font of those words for my poster.

If the image is isn't sufficient enough just google, "retro pepsi poster"

Thanks

Original is hand lettered but there exists

and

Which give you a reasonable starting point.
