In order to support assembly line like production of houses, Levitt limited the styles of houses, and common materials were used in all homes. One of the common materials that was used is what residents refer to as speckled paint. I didn't live in Bowie during the early days of the Levitt houses, but I have heard stories about the interior of some houses being painted completely with speckled paint. I've also heard recent stories about original homeowners selling houses that still contained rooms painted with speckled paint.
I had only heard speckled paint stories until I started doing home improvement projects on my Bowie house. This weekend I was working on a room remodeling project that includes replacing existing trim. I found some remaining speckled paint on the underside of the top door jam for the closet. Here it is in the picture below. The speckled paint can be seen on either side of the bi-fold door track.
On the back of some of the trim that I removed, I found a sticker for Hardware City. This wasn't original trim since Levitt and Sons used to make their own.
I also founds a 1956D Wheat Penny tucked behind some old trim - perhaps it's been hiding there since the house was built 43 years ago.
