This was probably printed in the early 1900s – 1907 – 1910 or so. “Commercialchrome” shows it was printed by Curt Teich in Chicago using their 4-color, halftone, lithographic process.
This vendor wrote their booth number and the price in ink. Annoys the hell out of me, but post cards are hard for vendors to control with too many people either altering the price or just slipping them into their pockets. It’s a hard-knock life, no?
