The top paper was stuck into an egg carton. It explains the coding system that is printed on every egg shell, noting quality and country of origin. For years, I've admired how Europeans document and clearly display in the grocery stores exactly where their food comes from -- I think it helps consumer awareness on multiple levels ("Where and who are the migrant farmworkers picking my grapes?" and "Gee, maybe I shouldn't buy this powdered milk product from China").
