Jewel grocery (or "da Jewels") is definitely a Chicago thing. If you're not from the Chicago area, you probably never heard of the chain. As a local Chicago store, they have been Chicago boosters and that has been shown with occasional baseball picture releases. They issued sets of Cubs players in 1969, 1973, 1977, and 1984.
The 1984 set was like the others and featured pictures of players printed on large 6"x9" paper. There are 16 pictures in all and they are all head shots. The cropping was odd with this set, as it looks like the players that were picked up during spring training or the season were cropped with just their head showing while those with the team for a longer time were cropped at the waist.
