Since 60-ies a picture stored on the mezzanine, along with another "carton", by which apparently, to hang on the wall. This "carrier" cardboard on the back of a signature (already "post-revolutionary") - "A. Morozov. Hunters around the campfire," for which actually makes sense to judge the name ...
Cardboard picture is rather thin, slightly flexible.
Photos of all this here.
