I'm slimming down my Russia & Soviet collections, and a lot of nice items will be listed as soon as time permits. Please remember that a small crease on a cover will be magnified by the camera and look more protruding on the photos and scans than in real life. Some reflections from the light in the room, and shadows from the iPhone as well - ie. these are not defects/stains/shadows on the stamps or covers, incl. pink and yellow hues. 

This listing consists of cover(s) as described above. Please see photo for details and ask if you have questions.
