My favorite brick since 2005 was the Elstan Little Jewel because I found four at my fathers home and for a while I was the only collector who had this brick. Dad was a bricklayer and accumulated firebricks for various projects. He got it from central Louisiana, or perhaps from the bricks I had gathered in Shreveport to build our home in 1979-80.
