I started a 'brick collection' a few years ago. I kept finding different styles of bricks from MINERVA BLOCK (Minerva, Ohio) These are the paver style bricks, not the house style. I started pulling them out of a creek and everyone laughed about me bringing them home. But, several people approached me wanting one. I gave them away at first, but soon started mounting a pen and pencil set on top. turning it into a desk set and charging for them. I am trying to collect enough for a patio area. I think it will only take me twenty years of collecting them to get enough to do the size I need!
