Pair of birds in the snowy mountains. The species pictured are brown-capped leucostictes but the picture could easily be used by anyone needed a black and white bird image.
Whenever the artist is Louis Agassiz Fuertes (1874-1927) there’s a significant chance the work features birds. This drawing is one of many Birds of the Rockies that date back to at least 1902.
