Regarding his base color. I bought him along with 6 others ranging from 9 1/2" to 11" at that the time. Most had varying degrees of cream colored bases, one had a very noticably orange base and this guy had a very bright yellow base color which was why I chose to keep him over all of the others. You won't believe what I paid for the whole group of 7. Makes me sick nowadays.
You can see pics of the group here:
