Looking to round out my collection with a bit of nostalgia. I'm a bit condition sensitive which has made this a challenge but would love any of the following:

-General Mills Cereal Boxes from the late 1970s featuring the ADPAC sticker promotion.
-Ben Cooper (Star Wars Edition) costume; any will do but looking for a nice box.
-Any print ads featuring the Early Bird promotion.

I know ebay has several of these but conditions are soft, and seemingly, the same stuff has been up for a year. Also know this won't be easy but any help would be appreciated!
