I want to start this material with a story that happened back in 1887 in the United States.
A distinguished looking gentleman in his 60's was shopping for vegetables and handed the cashier a $20 bill waiting for his change, the cashier accepted the money and put it in the drawer to change and return the change, when she noticed the ink was he was removing paint and it was staining his fingers that were still wet from the vegetables. Stunned, she stopped to think what to do. After a moment of wrestling with his doubts, he made a decision. The gentleman I am telling you about was named Emmanuel Niger.
A longtime friend, neighbor and customer certainly wouldn't give her a bill if it wasn't genuine so she handed him her change and he left the store; later he thought and reconsidered his decision, because in 1887, 20 dollars was a lot of money, so he sent for the police; one of them was confident that the note was genuine, while the other was intrigued by the ink that rubbed off.
Finally, curiosity and responsibility made them obtain a search warrant to enter Mr. Niger's home, in the attic they found the necessary instruments and facilities to reproduce 20-dollar bills, they even found a 20-dollar bill in the printing process, they also found 3 portraits of Emmanuel Niger, this man, he was a good artist, he was so good, that he had painted by hand those 20 dollar bills, stealthily from stroke to stroke, he applied the master touch with such skill that he was able to fool all the people, until discovered by a quirk of fate, manifested by the wet hands of a greengrocer saleswoman.
After the arrest, the portraits that Niger had done were sold at auction for $16,000 each, the irony of this story is that this man, this artist, used exactly as much time to paint a $20 bill as he did to paint a portrait. of 16,000, indeed this brilliant man was a thief in every sense of the word, incredibly the person who stole the most was himself, not only could he have been a rich man, if he had legitimately traded with his ability, but in the process would have brought a lot of joy and benefits to their customers. He was another in the unlimited list of those who steal from themselves, when they try to steal from others.
