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 slides in this set are labeled or dated but I believe they are from the early 1980s (at least the first three, not so sure about the last). The first three feature more photos of new construction. At first I thought the first photo may have been taken from the top floor of the building in the second photo, but the floor looks like it is concrete so probably not and also it looks like it is going to be a church or perhaps a school auditorium or something like that. I've been speculating the photographer may have worked for a construction company or contractor as lots of photos of newly built or under construction buildings have shown up in previous sets. The last photo was taken from the bank of a river or lake in the fall but that is about all I can tell.
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.
