Looking at the number of younger people in this hobby, I'm only 39, and I see alot younger in here and see more younger people out at auctions and meets when I can get to them.
This stuff is cross-generational unlike butter churns, milk glass, and Hop-a-Long Cassidy. Unfortunatley when the generation who grew up with butter churns and Hop-A-Long no longer collect there really isn't anyone there to pick up where they left off.
Collectibles in this field will continue to rise and keep interest due to popularity acorss the board.
Remember, buy what you love and enjoy the hunt.
