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/
This seems to be another set of photos of new buildings or buildings under construction. These aren't labeled or dated but like a few recent similar sets I think these are from the early 1980s. The first is kind of interesting in that it shows the interior of a building with a forklift and I think a Rolls Royce inside. The next is a building with "Webco Distributing" signage. Looking up that name today leads to a fireplace distributor based in Texas. Not sure if it is the same though. The next photo shows a rather nondescript building that looks recently finished or in the last stages of completion (the exterior looks complete anyway). The final photo shows what looks like a warehouse in the early stages of construction.
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.
