I'm not sure exactly which forum this would belong in, but here goes. I was just out in my yard and picked up a brick that has been there probably since the house the was built in 1955. I've moved this brick and others in the yard hundreds of times, encircling plant beds, etc. Today, I turned it over and because it was wet, noticed a name on it - Coffeyville. I did a little research and apparently, Coffeyville KS produced bricks, especially pavers, from the 1890s to 1930. So therein lies my question. Where would a single paver brick like that come from and how would it wind up in my yard on the southwest side of Chicago in an area that was mostly swampy until the homes were built in the mid 1950s? Most of the other bricks in the yard are an assortment of Chicago style house bricks and a few facing bricks. Kind of an odd mix. I will have to go out there and take a look at some of the others now! Why I've never noticed is a mystery also.
