No Pelt anti freeze, yours is a common transparent rainbo IMO. Please click on the link provided and check out the site, some of the I.D's are questionable but 99.9% are correct.

Anybody know what happened to Andy Mcloughlin's new Vacor Book that was in the works ?? No word from him yet, still waitin, ordered 2 copies, never sent any $ but ??
Here's a pic from the Peltier I.D. site. The ribbons are somewhat more pronounced, base is UV reactive. I don't believe yours will react to uv, just a little something off IMO

Definitely not a pelt Zebra, trans. green base rainbo IMO. Standard zebras have an opaque white base w/ black ribbons, usually containing some amount of aventurine but not always. Not seeing the uv effect ??
Nice marble Sherry, as far as the crease goes definitely a manufacture boo boo, all a matter of perspective on the value but generally, yes it will deduct somewhat from the total. Not really what would be called a cold roll crease IMO
