I've never actually seen a vintage 1940s fruit or vegetable brooch in person, but when I do you can bet I'll make a big commotion. Especially if I ever find those radishes! It seems that different jewelry companies favored different themes in their novelty brooches during this period - Trifari did a lot of flowers, Coro did a lot of birds, Boucher did a lot of fruit, etc. The insect-themed brooches from this period are especially interesting!
