Dear Mr. Graham,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located multiple photographic records relating to the Civilian Conservation Corps and the Works Progress Administration. Some of these photographs have been digitized and made available through the National Archives Catalog. Other records are only available in their original format. To access these records contact the National Archives at College Park - Still Pictures (RDSS) via email at email@example.com.
We hope this information is helpful. Best of luck with your research!
