And now this guy...as they says about Cher, "she's had some work done." And as the Grateful Dead say, "what a long strange trip it's been."
As part of the above trade with Marc, I traded him my better example (with tassels intact) of this pennant. The one one I got from Marc was pretty dirty. Marc cautioned me about trying to clean it, but I'm an idiot. I first just put it in soapy water. It maybe cleansed up a
little. Unable to leave well enough alone, I broke out the OxyClean. I figured "just a little Oxy; just a little soak." Within 30 seconds, the black just started dissolving off of it. The water looked like when you drop a paintbrush full of black acrylic paint into a glass of water.

I wish I had a picture, but I was in panic mode. I drained the water and started quickly dousing it with clear water. Amazingly, the black stains washed off...and the body was significantly whiter. It didn't look too bad. I put it on a towel to dry overnight.
This morning I checked it and all the black had turned to gray.

All the black you now see? Sharpie! I know, I know...major pennant foul. But I'm happy with it and happy with the trade I made with Marc. Have I learned my lesson? Perhaps.
