Black West End show ticket, row B seat 12

I lost my black Ticketmaster West End show ticket yesterday around 6:30pm outside the Prince Edward Theatre on Old Compton Street in Soho. It's a standard A6 paper ticket, glossy with the show name in red at the top, a barcode in the lower right with a small crease along the corner from being in my coat pocket when it started to rain. The seat is Row B, Seat 12, and the barcode is still legible though a bit smudged. This night meant a lot to me; I had saved up for months and it was a special treat with a close friend. If someone found it, I’d really appreciate getting it back.
