OLDS2 and OLDS3 was a crazy time for sketches. I sold all of my OLDS2 color sketches until the end when I ended up with 2 Lynch pulls and I bought the 2 artist returns. Most of my super nice B&W sketches were also sold to private collectors and were never put on eBay. I didn't want to sell them but it fed my box buying habit. I think for about a month straight I was overnighting about 50+ boxes a week.
With OLDS3 I ended up retaining more color sketches but did sell some really nice ones that I would have loved to keep but the market was just too crazy to keep them. I had to keep buying more boxes...LOL I knew if I had some great pulls it would pay for the boxes and I could retain a few for my collection. A lot of times I would buy 24 boxes, sell 9 sketches, keep 2-4 sketches, & then sell the rest on ebay. Wash, Rinse, Repeat.
