Will the Trojan horse trick work? / Keppler.

Alois Senefelder, the inventor of lithography, introduced the subject of colored lithography in 1818. Printers in other countries, such as France and England, were also started producing color prints. The first American chromolithograph—a portrait of Reverend F. W. P. Greenwood—was created by William Sharp in 1840. Chromolithographs became so popular in American culture that the era has been labeled as "chromo civilization". During the Victorian times, chromolithographs populated children's and fine arts publications, as well as advertising art, in trade cards, labels, and posters. They were also used for advertisements, popular prints, and medical or scientific books.

The Trojan Horse was a wooden horse said to have been used by the Greeks during the Trojan War to enter the city of Troy and win the war. The Trojan Horse is not mentioned in Homer's Iliad, with the poem ending before the war is concluded, and it is only briefly mentioned in the Odyssey. But in the Aeneid by Virgil, after a fruitless 10-year siege, the Greeks constructed a huge wooden horse at the behest of Odysseus, and hid a select force of men inside, including Odysseus himself. The Greeks pretended to sail away, and the Trojans pulled the horse into their city as a victory trophy. That night, the Greek force crept out of the horse and opened the gates for the rest of the Greek army, which had sailed back under cover of darkness. The Greeks entered and destroyed the city, ending the war. Metaphorically, a "Trojan horse" has come to mean any trick or stratagem that causes a target to invite a foe into a securely protected bastion or place. A malicious computer program that tricks users into willingly running it is also called a "Trojan horse" or simply a "Trojan".
