I'm at Fair Park this very moment -- c'mon, you know why. But speaking of, Friend of Unfair Park PeterK -- who clearly spends more time on eBay than should be allowed, God bless him -- has come across this magnificent find: three original photos of the 1936 Texas Centennial Exposition taken by none other than Official Photographer John Sirigo, whose images from the event remain among the most iconic photos ever taken of Fair Park. They're a steal at $9.99, though I don't expect them to remain at the nice price for long.
Update at 12:50 p.m.: Seriously, someone should give Peter a commission. Bidding's now up to $51.
