See the previous post in this series here.
I made some impulse buys after getting a new scanner and picked up a huge batch of slides a while back. These pictures span from as early as the late 1940s to as late as the early 1990s. These were from Goodwill and eBay (sometimes via estate sales). There are many thousands of these slides. I will be scanning some from time to time and posting them here for posterity.
This set continues a large batch of slides that originally came from an estate sale and appear to have belonged to a locally well known photographer from the Spokane Washington area named Leo Oestreicher, or perhaps a friend or family member of his. These slides contain some landscape and portrait photos but also a lot of typical snapshot photos. Here's an article on him from 1997 which is the only info I have found on him: http://www.spokesman.com/stories/1997/jan/04/photos-of-a-lifetime-museum-acquisition-of-leo/
None of the photos in this set are labeled or dated but it looks like another set of photos of buildings under various stages of construction from the early 1980s. The first photo shows what looks like a warehouse under construction. The second shows an apparently recently completed office building. The third photo is the most interesting to me. I assume the garage or perhaps showroom is recently completed construction but the more interesting items are the old Apache campers. The last photo looks like maybe a dry dock area for boats or at least an enclosed area to keep boats out of the weather. My best guess is that the photographer was working for a construction company or general contractor and that these photos were to show examples of work or something.
The entire collection that has been scanned and uploaded so far can also be found here. This also includes higher resolution versions and versions with post processing.
