In 2014, Michael Burge Smith painted a nearly 1,000 square foot (93 m²) mural depicting the Swiss and German Alps for the Eichentopfs.
Smith and Gretchen collaborated on the concept after he saw the building's blank exterior 64-foot (20 m) wall one year prior and showed her samples of his work.
Before painting the kitchen's outside wall, Smith completed an interior mural at Otto's  and another at the Eichentopfs' daughter's house.

Most of the mural, inspired by the Eichentophfs' passion for skiing, was completed by Smith; his business partner Kenny Spurlock assisted during the early stage, but died in August 2014.
Smith worked on the mural over the course of two months, mostly between the hours of 9 pm and 3 am.
He said of his working style: "I love the freedom of being able to pick my hours.
And I travel with my band all over the world, so I fit painting in when I have time."
Smith has completed many murals in Portland and has taught painting to high school students in Oregon and Idaho.

In February 2019, Smith returned to paint a "magical" 33-foot-long mural on the building's north side.
The fantastic art depicts German folklore and features castles, fairies, and flying horses around a central "tree sprite".
The "Lord of the Forest" figure is painted over a column and onto nearby benches, and the bark was painted by Smith to be interpreted as either "friendly or fearsome".
According to staff, Smith typically paints seasonal murals four times per year.
