What is your oldest piece of Tupperware?

I have one olive green cannister left from a set of 4, still use it for my rice, don't know what happened to the other pieces!  have the old white salt & pepper shakers, won't give them up for anything! and the gold deviled egg tray.  Have many other newer pieces, love the rock n serves.  I find pieces at rummage sales here and there, and always put them to good use.   One thing I bought that I haven't used, (got it for $2 at a rummage sale, that lady didnt use it either) is an oval piece with 3 stackable trays, I guess it's for sandwich ingredients. 

My oldest is my red lunchbox. Well over 50 years old.LOL It is currently recycled to my sewing room for filled bobbins. I would love to find another one but they only had this for a short time. I also have a couple of the ice tea tumblers and ice tea spoons that stay in the camping equipment along with the large and small salt and pepper shakers.

The most used are my big yellow and green bowls. These come out for all family gatherings and picnics. I love that they hold double and tripple batches of salads.

My mom brought this spatula when we emigrated from England in 1967.  It is fantatic because it is all one piece so there is no place where the handle meets the "spade" where germs and food can hide!

 That I know to, Tupperware never sold this piece in the USA so when I went to visit my cousin in England in the early 1980s, I ordered a dozen of the spatulas there and she shipped them home to me...they are an awful burnt orange color but still wonderful :)
