The first store, built 1889, is from the same “Illustrated History” book. This was the original store in Nelson (re-named Danville)
The second store – I believe mis-labeled 1889 was the temporary store on the US/Canada border (Note that they hauled the Big Sign to this operation!)
After a fire consumed the original store, a replacement 2-story structure was built in it’s place about 1900.
btw, the “Nelson Brothers” were actually Uncle (Ole B.Nelson) and his Nephew (Peter B. Nelson). Not brothers, although a younger brother of Peter B. Nelson, Nels, came out and worked in the store in 1899.
