It looks like a homemade font that resembles Murray Hill done with a felt tip pen.

"CAC" was Create-A-Card, from American Greetings. According to this site, these kits may no longer be sold. I have a bunch of the CAC fonts in my Script Font ID Guide, but this apparently isn't one that I have.

I did a search on 'CAC' with Fontseek and saw one called 'Pinafore' that resembled this at first glance, but it turns out to be more of a connected script.
The CAC idea might still be right, but my search didn't find it.
