As far as putting the 20th anniversary logo/seal on the actual anniversary pieces like HL 566 Shinnecock, I think it's fine. However, I feel putting the 20th logo/seal on ALL the 2011 limited pieces should be done only if it appears in a less obvious location and size than the anniversary pieces. Otherwise, the logo/seal may become a distraction to the beauty of the 2011 limited pieces and a form of unwanted advertising in your face. Maybe even a special sticker on the base of the other 2011 limiteds with a colorful logo/seal would be more classy than being put topside.
