After my father died, we found a briefcase of his,which had two bricks in it. they have "JMC"
on them. My mother had no knowledge of them.
Anyone have any thoughts? Dennie


  1. Hi Dennie,

    JMC was a brand mark of the Jova Manufacturing Company. According to George Hutton in "The Great Hudson River Brick Industry," JMC was the brand used for Jova brick made after the Jova Company bought out the Hutton plant in East Kingston in 1965.

  2. Jova also made the brick with JJJ on it. It was made in Roseton, NY in 1900. He also made one with JOVA on it in Roseton in 1884
