Condition: some mild edge and corner wear, a few tiny areas of paper loss along edges
In doing a bit of research on this card, I learned the brief (and interesting) history of this city. Vanport was a public housing development built near Portland in 1943 for WWII shipyard workers. At the time, it was the largest public housing development in the US. In 1948, its population was around 50,000, with many African American residents.
During the 1920s, Oregon had one of the largest and most active chapters of the Klu Klux Klan outside of the Deep South. In 1940, there were fewer than 1800 blacks in the state, but by 1946 there were 15,000 in the Portland area (mainly Vanport) due to newly-created manufacturing jobs in response to the war.
The community was located in a low area between Portland and the Columbia River, and was protected by a dyke. In 1948, the area experienced record spring runoffs, causing a swelling of the Columbia River. On the morning of May 30 the Housing Authority of Portland issued the following statement: Dikes are safe at present. You will be warned if necessary. You will have time to leave. Don't get excited. However, at 4:17 pm the dyke broke and a 10' wall of water inundated the city; the city was a complete loss and 15 (or 16, depending on source) people were killed.
The handling of this disaster has been said to parallel that of New Orleans after Hurricane Katrina, with the allegation that little effort/aid was expended due to the racist attitudes of public officials. This area is now the site of Delta Park and the Portland International Raceway.
