Depression Glass, Carnival Glass, Stoneware Pitchers and Churns, Handmade Quilts, Hand Embroidered Linens, Fiesta Ware, Mickey Mouse Stuff, Snoopy and Woodstock stuff, Old Jewelry - mostly bakelite, New Jewelry, Antique Perfume Bottles, Antique Furniture.... EIEIO !!
Actually, being the only child of an only child I seem to have become the curator of our family's museum of junk. Some of it's rather nice junk.

I have ton's of stuff that belonged to my great-great-grandparents.....
Edited because I forgot about the shotglasses, cigarette lighters, NASCAR stuff, and the McCoy and Hull pottery.... I have WAY too much stuff !!

I suppose that I also collect children. I inherited FOUR of them when I married for the second time and then I got pregnant. We were hoping for a "six-pack", but we only have five
Edited again to say that the most important thing of all to collect is memories...
