The Harvest Carnival medium canisters was introduced by the Indiana Glass Company in the mid to late 1970's. It measures 8 inches tall (to the top of the lid) and 5 1/2 inches across the uncovered top.
I wish I could say these are plentiful, but they are not.
Interest and sales in the Harvest carnival was declining. The small canister (candy jar) had been a HUGE success sales wise. In an effort to "revive" sales, the Indiana Glass company introduced the medium and large canisters. Their thinking was that everyone who had bought a small canister would buy the medium and large ones to complete the set. This did not happen and the medium and large canisters had a short production run. They are tough to find.
The medium canister was made in all three of the carnival colors, blue, gold and lime green.
