Eastern Color
Eastern Color Printing are given credit for the birth of the comic book. Funnies on Parade and Famous Funnies were the two comics that gave birth to the medium. Eastern Color published comics from 1933 through the mid 1950's. In 1973 it ceased printing comics for other companies.
In the early 2000's Eastern Color closed it's doors.
