I discovered an interesting phenomenon when opening this piece I framed about 15 years ago. The adhesive on the old-style TruVue sticker outgassed right through the latex-infused black dust cover paper I was using back then, and left a stain on the FC backing board. My shop sticker did not. BTW, this was a good paper, not the cheesy kind that fades to purple. ...(I use acid-free gray kraft now.)
