As explained in my post on Mystery Box #2 (in which the first 50 slides in the box are displayed), these are a non-cohesive collection of generally well maintained European glass stereoviews. Sold as-is, at a low per-slide rate. Approximately 150 slides at approximately $3 apiece.
This would be a good starter collection for someone collecting art for art’s sake, for someone who is just looking to fill Taxiphote trays, or for someone brand new to collecting 45x107mm European glass stereoviews. Contact me if you need me to list a simple handheld viewer to go with these.
Each slide is preserved in an archival-quality thick polypropylene sleeve.
