Yup, that's them. Harvey were a straightforward comics publishing house until they started licensing the characters of Famous Studios, and of course their biggest hit Casper the Friendly Ghost. Harvey Comics really was the house that Casper built. Animators became comic artists, and the publishers developed a huge range of Casper comics -- as well as creating a whole range of comics based on other Famous Studios characters like Little Audrey and Baby Huey.
Then in 1949 came Harvey's in-house creations like Little Dot. Little Dot was a little girl obsessed with dots. She was so successful that she launched a bunch of spin-offs like Richie Rich and Little Lotta. All of these characters were made in the Casper vein; they were family friendly, they were mono-maniacs and they were drawn in Harvey's house style of giant heads and fat legs.
Oh yeah, and they all suck.
