This menu dates from before 1909, when NP began selling its Great Big Baked Potato. Other than the fact there are no giant spuds on this menu, there’s not much to date it except for prices. Update: This menu is from the 1920s as indicated by the name L.K. Owen, who began working as NP’s dining car superintendent in 1921. The Great Big Baked Potato must have been advertised on a separate card.

A sirloin steak was $1, which if the menu were from 1908 would be about $25 today but if from 1900 would be nearly $30. From 1890 it would be closer to $25 again as the late 19th century was a deflationary period which ended in 1899. So I’m inclined to think either 1890 or 1908.
