Ok, so it's for CHEM 13 news, Dept. of Chemistry, University of Waterloo, Ontario, Canada. ;->
This from Jenn Shmitt, the co-ordinator:
It's that time again... more Periodic Table Print Project News.
The September issue of the Chem13 News features our project (we're even the centerfold!). They were so inspired that they have started their own periodic table project--open to more media than just printmaking-- as part of the University's celebration of the Year of Chemistry, 2011.
