Just read this on MoPo, from Tod Spoor of MPGrading.
It's been up for about 2 hours. I'm sure he won't mind me posting it here in it's entirety.
Simply titled "Woodstock Style C Results"
"Hello MOPO,
The results from the Forensic testing is in. The Woodstock style C NOT real!!! You called it from the beginning Bruce! I want to thank the 5 Dealers/Collectors that sent in either their Style B or Style C Woodstock posters for comparison testing. I will be returning them to you tomorrow.
Below you will find an abbreviated test results. I will have a more detaile report along with pictures of the staining up on our website hopefully by tomorrow.

Softwood bleached kraft – Hard Pine (Except Red & Scotch)
Hardwood bleached kraft – Redgum, Sycamore, Yellow-poplar, Blackgum, Maple
Coating flakes are yellowish
Appears to be a Southern Mix
Spot test implies this sample is most consistent with paper from before the late 1980’s.
