songbird replied to arizhnt's topic in 1893, Chicago, United States - World's Columbian ExpositionI also have a 1893 World's Fair Souvenir Pocket Knife passed down from my grandfather. My knife has carved Ivory on both sides. One side has the three Columbus Sailing Ships and the other side has a large building and the dates 1492 and 1893. I can't read the manufacturer markings. I am also looking for information.
