World Columbian Portfolio--Eight Books of 40 Pages in 1893/Just the Flyer Today

I am only offering this great advertising piece from the Columbian Expo, not the 320 pages of artwork in a portfolio format it offers. Each 40-page folio was available for a dime! That was even pretty darned cheap more than 130 years ago. Having been involved in publishing and printing my entire life (I began working at a printing business in high school which seems like it was about as long ago as the Columbian Expo), I cannot imagine printing a full color, high quality bound 40-page publication that one could buy for a dime.

What is for sale here is the advertising promo piece shown in the photo, 8.5x11 inches.
I wouldn't want anyone to think I was selling the folios advertised in the 1893 flyer.
