I recently purchased three Ohio bricks (meaning that the word “Ohio” is stamped on them!) that I thought were really neat to have. I knew I had some other older red bricks with different names stamped on them so I wanted to add the Ohio bricks to the small but now growing collection.

Also sharing some great links that I found on the Internet about bricks made in Ohio:
