I bought a very cool deck of Beatles playing cards that I found in the music store where I was leasing my middle daughter a clarinet. It has photos (international) of all their single covers.
I also got my son a bunch of Beatles notebooks and folders at Wal-Mart, including one with a Sergeant Pepper cover, Abbey Road cover, and Hard Day's Night cover. Hoping he can convert some young (fourth-grade) Beatlemaniacs!
Unfortunately my daughters' school requires that they have plain, solid color notebooks and folders.
