The World Columbian Exposition of 1893 commemorated the 400th anniversary of the landing of Christopher Columbus in the Americas. The Post Office got in on the act, issuing a series of 16 stamps depicting Columbus and episodes in his career, ranging in value from 1¢ to $5 (a princely sum in those days). They are often considered the first commemorative stamps issued by any country.[citation needed] The stamps were interesting and attractive, designed to appeal to not only postage stamps collectors but to historians, artists and of course the general public who bought them in record numbers because of the fanfare of the Columbian Exposition of the World's Fair of 1892 in Chicago, Illinois.[citation needed] They were quite successful (a great contrast to the pictorials of 1869), with lines spilling out of the nation's post offices to buy the stamps. They are prized by collectors today with the $5 denomination, for example, selling for between $1,500 to $12,500 or more, depending upon the condition of the stamp being sold.[citation needed] Another release in connection with the Columbian series was a reprint of the 1888 Special Delivery stamp, now colored orange (reportedly, to prevent postal clerks from confusing it with the 1¢ Columbian). After sales of the series ceased, the Special Delivery stamp reappeared in its original blue.
