The Evolution of Weber Costello, Part 1 (Holbrook)

As it turns out, Webber Costello Co. was a school supply company, and the stationary company is one and the same. They stopped making maps and globes.

Cynic that I am, I suspect they did not own the rights to the maps and globes they published, but were simply copying and/or reprinting. In the day they got started, most publishing in the U.S. was basically public domain, and that they were being made for educational purposes, even for profit, limited fair-use would have protected them.
