The topper features Heroes of Cybertron Rodimus Prime and Arcee, on a wooden stand with a custom veil, bouquet, bow tie and tux tails. It's pretty adorable, if I do say so myself. If you wind up winning, drop me a line and I'll see if I can't do something extra-nice for you.
It's up on ebay now, with a starting bid of about $25, which is more or less the cost of the materials involved. It's for a good cause, so place a bid if you're interested. You can also check out the We Dream For Jeanne blog.
