Seltzer worked as a machinist for the Great Northern Railway (U.S.). In 1897, he began painting alongside Charles M. Russell. Seltzer decided to paint independently from 1921 onward. He worked as an illustrator for The New York Tribune in 1934, and he exhibited his work in Seattle in 1936. He did 275 paintings for physician Philip G. Cole. He did over 2,500 paintings and illustrations over the course of his career.

Seltzer did both watercolor and oil paintings, and he depicted life in the American West, including animals, cowboys and historical events. He also painted pioneers like Meriwether Lewis and William Clark. Seltzer did a painting for the Grand Masonic Library in Helena. President Harry Truman received one of his paintings as a gift on his 1950 visit to Montana. His work was exhibited at the Gilcrease Museum in Oklahoma in 1957.

Seltzer married Mabel L. Cleeland in 1903. They had two sons, Carl and Walter, and they resided in Great Falls.

Seltzer died on December 16, 1957 in Great Falls, Montana. Some of his work is in the permanent collection of the C. M. Russell Museum Complex in Great Falls, the Art Institute of Chicago, the Gilcrease Museum in Oklahoma, and the Tacoma Art Museum in Tacoma, Washington.
