My weakness is in the early American bottle designs. I love Owens and Ball, but am learning slowly to recognize the art of very early blown glass bottles. I live in an area of the U.S. that has many Owens artifacts due to the direct links with Ohio and Louisville Kentucky. There are lots of early bottle makers in this area. There isn't a scouting session that goes by without a cool find from Owens or Knox. I have many of pieces to slowly add as I research and go through them.
