Roanoke artists Josh and Libby Nolan-Shafer have been on a roll.

Last month, city dignitaries presided over a ribbon cutting for the couple’s latest mural, which graces an office building along the greenway near Peters Creek Road. In recent years, their paintings have popped up along walls near the City Market Building and Golden Cactus Brewing.

But they’ve wasted no time in promoting more portable works of art. While murals remain the Nolan-Shafers’ number one priority, the couple has found surprise best-sellers in their number two.
