Pre-PowerPoint US Defense Slides
- mxfh 3y agoSam Biddle: «I found a guy on eBay selling boxes of Cold War-era photo slides from old Pentagon presentations for a buck each so I stocked up. Working on getting them scanned this week/will share the finished product. There are a couple sets from USAF, one from the Navy, and one from NORAD OK, the original four boxes of slides are uploaded to @internetarchive in both JPEG and uncompressed TIFF formats. I'll scan the other 60ish boxes down the line and keep whoever is interested updated as best I can. Enjoy.» https://twitter.com/samfbiddle/status/1669089736168730628?s=20 https://twitter.com/samfbiddle/status/1669089736168730628?s=...
