Here are the works of four of the best painters of the Texas Bluebonnet ever to pick up a brush.  

Each is rendered on a 3.5 inch square piece of genuine slate. The same stuff that was once used to roof fine homes and protect families from the elements will now do the same for your tabletops as coasters. 

The artists are Julian Onderdonk, Dawson Dawson Watson, Clara Pancoast, and Porfirio Salinas.

They come in a small burlap sack, which makes a nice gift presentation, and they are backed with cork, so they won't scratch your surfaces.

There's only one problem - they look so good you won't want to hide them under a drink.
