One More 1972 Unopened Pack Down

I am down to needing just seven unopened Kellogg's packs from 1972.  Does anyone have HOFer to trade?  

I don't have many unopened packs from 1971 and 1975, just like lots of others.  I've gotten a few from 1970 and 1974 and decent amounts from the other years.  

Do 1982 and 1983 single-card unopened packs really exist?  I was in college, so I didn't get to chase down cards while eating cereal at home.  Can someone send a picture of one?
