If today's economic outlook has you (or your grandparents) harking back to the Great Depression, take heart: A roster of free public events this weekend is designed to evoke the hopeful spirit fostered in the wake of those grim days.

The Posters for the People Expo Festival marks the 75th anniversary of Franklin Delano Roosevelt's New Deal - an alphabet soup of programs created to restore the nation's spirit, as well as its economy.

Chief among the New Deal programs was the Works Progress Administration (WPA), which put everyday men and women back to work building schools, roads, bridges and post offices. That legacy is visible today in the Golden Gate Bridge, the Blue Ridge Parkway, and the Philadelphia airport - all WPA projects.

But FDR's New Deal also recognized that the Depression was more than economic - it chipped away at our souls, as individuals and at our collective spirit as a nation.

So the WPA had a strong arts component. Unemployed artists, musicians, actors and writers were hired to create plays, songs, books and films aimed at rebuilding national pride and community spirit.

And the WPA hired other artists - poster makers - to help publicize all the New Deal efforts.

Millions of silkscreened posters hung in bus depots, shop windows and schools, urging citizens to value themselves, respect their neighbors, and find confidence in government.

Community spirit was at the heart of FDR's New Deal and its goal to promote a hopeful and strong America. And in that spirit, the Posters for the People Expo Festival is free and open to the public. Here is what's planned:

Ongoing

A Living Archive of WPA Posters is available online. WPA artists designed more than 35,000 posters, but until now only about 900 were available for viewing online at the Library of Congress.

Since 2002, the Social Arts - the nonprofit arm of the local company Design for Social Impact - found and digitalized 1,000 additional WPA posters. A Web site displaying all the posters will be launched this weekend.

A field day will be held from from 11 a.m. to 3 p.m. at FDR Park, Pattison Avenue and South Broad Street. Bring the family out for an old-time field day with sack races, a doll-and-buggy parade, music, guided hikes, and a cookout.
