Here's a newspaper ad that ran in papers in Q territory in early 1900. Is this the earliest calendar produced by the railroad?

Do You Want a Calendar?
The biggest, the best, calendar ever issued by any American railroad is now being distributed by the Burlington Route.
It has twelve sheets, one for each month of the year. On each sheet is a striking illustration of some feature of the Burlington's service or of the territory reached by its lines -- the government fast mail running at full speed; a tourist car on
its way to California; engine 1591, the largest passenger engine in the world; a library car; a compartment sleeper; the Burlington station at Omaha; a dining car; a monster freight train; Estes Park, Colo.; the plunge bath at Hot Springs, S.D.; Yellowstone
Falls, etc.
The drawings from which the pictures were made are by Louis Braunhold, of Chicago, and cost several hundred dollars. The size of the calendar is 22 x 28.
The dates are in big type which can be read at a distance of 50 feet. For business offices the Burlington calendar is simply invaluable. Purchased in large quantities, the calendars cost the Burlington Route 27 cents apiece. With postage, packing,
etc., they represent an investment of about 35 cents. Our price is 25 cents -- 10 cents less than cost. Write for one; stamps will do. If it is not satisfactory, send it back and your money will be promptly refunded.
