Vintage 70s Avocado Green Tupperware Servalier Canister Set

Vintage 70s green Tupperware Servalier canister set. Four pieces, three have lids, all show signs of wear, see photos for details. I don't believe I would use these for food at this point - unless they were in packaging as the bottoms inside of a few are rough. Please see photos for examples of wear - still display nicely! Largest measures approx. 9" tall, 7.75" wide.
