Seller: ist189o (323) 100%, Location: New York, New York, Ships to: US, Item: 333495173680 These are new old stock (ie new items which have not been available for purchase for quite some time) unused, archival Mylar 4x7 stereoview sleeves. Openings on both short ends. They are different from typical sleeves in two ways: 1) There is a tab on the top of the sleeve that can be written on, so you can flip through a box full of views without having to take them out to find a specific view. 2) While the front of the sleeve is crystal clear, the back is frosted and not as easy to see through, as shown in the attached picture. These sleeves are not for everyone. I am not interested in the tab so I do not use them. A small partial box of them was included with a grouping of stereoviews I bought a while back, and I am posting some of them for sale for those collectors that have long sought these out (the only reference to them I was able to find is an ad in the March/April 1981 issue of Stereo World). If you order them, make sure you know what you are buying - there are no returns. If you buy more than 1 lot of 50, ask me to send an invoice so I can weight them out and recalc the shipping. Ships to US only (email me if in another location), ebay adds tax in most locations. Sorry, but the stereoview in the pictures is NOT included.
