Hi Scott,
I've always thought the Ritchey "Dove" was an intentional change too, or perhaps it didn't show up as well on the first few printings, so they made it more prominent in the later print runs... I know many people believe it's a mere coincidence that the cloud appears to be a "Dove", the team’s nickname, but not me... I only have access to my photobucket, so I can't post a lot of pictures, but here are a few:
Be well Brian
PS I will try to post more later
