I can't find a license for a font from Adobe, the font itself isn't even on the site!

More info: the web site WHATFONTIS is mistaken, when it says this is an Adobe font. But I checked: for a while you could license Font Bureau fonts from the Adobe Fonts service. But Font Bureau ended their relationship with Adobe, so you now have to license from Font Bureau.

Illustrator doesn't include any fonts today. None at all. The fonts it shows are the fonts installed in your system. These can come from

- included with the system

- activated in Adobe Fonts service

- purchased/downloaded

- included with other apps 

There are millions of fonts! Finding them can be tough. I have found Showcard Gothic, offered for license by the owner, Font Bureau. Showcard Gothic · Font Bureau · Fonts · Type Network
