Around 2000, Scholastic published a series of picture story books adapted from Cartoon Network’s Powerpuff Girls. The main typeface on the covers (and, for some books, also on interior pages) is Whachouse. Designed in 1993 as part of House Industries’ General Collection, Ken Barber’s bold wide semi-slab appears to be inspired by faces like Benguiat Interlock. A decade later, in 2004, House Industries would collaborate with Ed Benguiat on a more advanced interpretation of a similar design, Ed Interlock.
Whachouse is typically used with one or more colored contours, and a curved setting of the subtitle. All smaller text is in Zuzana Licko’s Base 9 Sans.
The Powerpuff Girls logo is custom drawn and doesn’t use a font. There at least two fonts based on it, though: Powerpuff Girls by Tom White and Powerpuff by Neale Davidson of Pixel Sagas (2011–2014, revised in 2015 and renamed Utonium). The Cartoon Network logo that’s partly visible in the top right corner uses Eagle, see the dedicated post.
