OK, here's an actual prop/costume piece from DS9. I got it at a charity auction, back when I was in Sid's fan club. It's the bow tie he wore in "Our Man Bashir." He auctioned it off, autographed it and handed it to me.
I have a picture, in an album somewhere, of the event, but I can't be bothered to dig it out and scan it into the computer. At least, not right this second. But I could find it, if someone wants proof.
