I found the article to be fascinating. Of particular interest to me was the following line:
"For wet watermark detection, many experts prefer to use Ronsonol brand lighter fluid, which is both toxic and flammable."
So, some collectors put their stamps in direct contact with lighter fluid? That simply amazes me. I imagine it does not damage the stamp, or else collectors wouldn't do this. I also wonder how that collecting community first discovered it was a safe method to use..."hey, guys, watch this."
On another note, I often found myself thinking about T206 collectors while reading the article. It seems as though there are quite a few traits they have in common with the stamp collectors written about on Linn's. They desire to determine sheet layouts, look for variations, they disagree over the "legitimacy" of certain variations, etc. It sounded very familiar.
Glad I had time to read this. One of the few bright spots about being home with the flu.
Best regards,
