Q: This was my grandmother's pitcher and glass. It's from the 1893 World's Fair and has her name engraved on the other side. Can you please tell me what this may be worth?
A: The World's Columbian Exposition, also called the Chicago World's Fair, was held in 1893 to celebrate the 400th anniversary of Christopher Columbus's discovery of the New World. It was one of the great World's Fairs of the 19th century. The fair covered almost 700 acres bordering Lake Michigan and over 150 buildings contained exhibits from many nations.
Your grandmother's souvenir pitcher and goblet set is early American pressed glass in a pattern known as Ruby Thumbprint. The pattern was first made by Adams & Company of Pittsburgh in 1891. The pattern was originally called Excelsior, and was listed in catalogues as the XCLR pattern. Pieces were sold either plain or engraved. Thumbprint was also produced in all-clear glass and called King's Crown. Many pieces of Ruby Thumbprint glass are still found with the name and date of the fair and the name of the owner. It was inscribed at the fair while you watched.
Your grandmother's glass has great sentimental value for your family. To a stranger the two pieces are worth about $225.
