Del has painted over 100 murals, including murals at the Denver International Airport, Hot Springs, SD, the Grand River Casino in Mobridge, SD, the Dakota Sunset Museum in Gettysburg, SD, the county courthouse in Foreman, ND, and the Royal River Casino in Flandreau, SD. One of his military murals can be seen at Ellsworth Air Force Base in Rapid City.
An Iron Cloud historical mural adorns a community wall in Ashley, N.D. Because the Ashley mural was such a large project, his wife Frieda pitched in with background and other painting. She is an artist herself. Del says she is “really good with Native American portraits, sceneries, flowers, horses…most anything". Iron Cloud also designed the logo for the B1B bombers at Ellsworth Air Force Base by Rapid City, SD which they still use for billboards, caps, and t-shirts.
