Shruti, my other buddy in the throes of wedding planning, posed this question recently, and its one I posed to the L.A. blogosphere — where could one find vintage (i.e. old) Los Angeles MTA subway/bus tokens? No one has answered me yet, but Shruti has her eye on a set on eBay, which she plans to fashion into cufflinks for one of the groomsmen in her wedding this coming July.
It occurred to me that this is yet another tiny detail that brides attend to — and it may be small in the grand scheme of a large wedding, but I imagine that its definitely something that sticks in the mind of the wedding attendant who receives the gift.
