Hello and thank you for the warm welcome! I am fairly new to collecting, around 2 years, and feel i have a lot to learn! I have a small collection of skillets so far. My favorite pan in the world is my #12 Griswold slant Erie, which i cook in a couple times a week. As far as collecting, that is my favorite series. I have noticed a bit of difference in some of the handles, some being flatter and more concave. Again, many thanks, and cant wait to look, listen and learn! Beth :)
