In this veggie-themed envelope.
The stamps are from a Farmers Market set issued in summer 2014. I think they are a nice se-tenant set. They were criticized for the somewhat high prices shown on the produce, with people saying that it gave the impression that farmers markets are expensive and only for the well-off. I really don't think that such a small detail on a stamp is going to influence anyone, plus I am sure inflation will take care of that eventually.
