all good ideas above. I'll add this, which I suggested in the past: that the on-line logo include:

(1) the date the Club was founded (1988)
(2) the fact that it has over 2000 members
(3) a link to the club site/application blank
(4) a link to a new Club code of ethics specifically related to auctions and sales. It could cover a host of (only; don't get excited) guidelines for things like rare, insurance, returns, guarantees, etc.
