BUFFALO, N.Y. (AP) — Propaganda posters from World War I are the focus of a new exhibit opening at the Buffalo and Erie County Library.

The exhibit is opening Saturday at the system's Central Library in downtown Buffalo. It tells of the city's role in America's war effort in terms of personnel, civilian support and industrial production.

Items from the library's own collections will be on display, along with World War I artifacts on loan from other institutions and collectors.

The highlight is the library's extensive collection of WWI posters, donated a year after the war ended in 1918 by Edward Michael, a prominent Buffalo businessman.

"Buffalo Never Fails: The Queen City and World War I" commemorates this year's 100th anniversary of the U.S. entry into the war. The exhibit runs until 2020.
