Up into the Space Needle the ANTIQUES ROADSHOW team went for a chat about World's Fair posters with expert Nicholas Lowry. With the Seattle, Washington, sky setting the stage, Nicho delved into the subtleties of these graphic treasures.
The poster on the left is from the 1939 World's Fair in New York featuring the Trylon and Perisphere; it is especially rare, valued between $2,500 and $3,500. The one on the right is an unofficial one from the 1962 World's Fair in Seattle and depicts the Space Needle and Pacific Science center, valued between $600 and $900.
Bringing science, technology, and future thinking together into one event, the World's Fair serves as a platform for getting in touch with what industries could become, what laws of physics they could defy.
