This is a set of 8 pins that my Grandmother had in her estate. I can see that the frog and the woman cameo. The pin that has a knight in it is marked Coro.  I can't be sure on the other pins but they could also be Avon.  I really do not have any history or knowledge about them except that they are all pretty. The round wreath pin is missing some small pearl type gems but you have to look closely to tell.
