Stacy, one of the things I like best about Vitro is the attitudes of the men who thought I was a nut because in 1992 I was searching for Vitro along with Akro, Peltier, etc. At that time, "real collectors" didn't look twice at Vitro. The guys saved them for me and when they came to Texas they gave me Vitros. They were considered worthless. I just kept saying "thank you". I bet now some of those guys would like to have them back. It took me a while to collect enough that I could see more colors in one marble than I saw in Akro or Peltier. And not just more colors in one marble, but MORE COLORS period, MORE VARIETY too. I love Vitro.
