I have several Reader's Digest bookmarks in my collection and I particularly love the "Select Editions" ones. These bookmarks were released by Reader's Digest to celebrate the 60th Anniversary, in 2010, of their Reader's Digest Condensed Books (the former name of "Select Editions"), first published in 1950.
The art on the front of each bookmark comes from the cover of that original volume. The information on the back of each bookmark includes a quote from one of the books featured in that volume.
Thus far I have six of these bookmarks. I am not yet sure how many were produced.
