In 1927, Frank Nugent Freeman published a collection of books titled "Correlated Handwriting," published by Columbus-based Zaner-Bloser Publishing Co.
An image in one of the books in the series showed a classroom setting in which the materials associated with the handwriting program were demonstrated.
The classroom was at R.L. Stevenson Elementary School in Grandview, shown in this 1929 photo.
The labels in the photo refer to the Correlated Handwriting Compendium, the Zaner-Bloser Penholder, the Teachers' Manual, the Penmanship Strip, and a student using the Handwriting Scale, all components of the Correlated Handwriting program.
