In the late 1970s Fleer produced series with MLB team logo stickers. While the design was very similar over the span of a few years, the 1979 set was the last year of that design, with its distinctive feature being a puzzle on some backs that joined to form an image of the 1978 World Series. Two unopened cases of these stickers contain 12 boxes of 24 pieces each (with gum, of course), each sealed at the top with the original heavy duty staples, making clear that these are unopened and contents are presumed to be NM.
