The sign was on a busy city road and with the increased attention of the assassination was probably busier than usual but you reckon someone came along and swapped the signs, hilarious!hnM
EMMET J. HUDSON - WC TESTIMONY (7/22/63)
ATTORNEY LIEBELER - "Were you the groundskeeper of Dealey Plaza on or about 11/22/63?"
EMMIT J. HUDSON - "Yes, I have been there about 6 years."
------------------------------------------------------------------------------------------------------------------
LIEBELER - " There are 2 signs in Picture No. 18, one says "R.L. Thornton Freeway, keep right", and the other one says, "Fort Worth turnpike, keep right."
HUDSON - "There WERE 2 of them that wasn't too far apart right through here - them signs WAS right along in here, and the other one was either further up I guess. It's not in that picture - I don't believe now. THEY HAVE MOVED SOME OF THE SIGNS. THEY HAVE MOVED THE R.L. THORNTON SIGN AND PUT UP A STEMMONS SIGN.
LIEBELER - "They have?" "They have moved it?"
HUDSON - "Yes, sir"
LIEBELER - "That might explain it because this picture here, No. 18 was taken AFTER the assassination, and this one was taken AT THE TIME - No. 1.
Nobody would be more aware of the Absence/Shifting Position of Signage sitting on The Knoll, than the individual that had been paid to landscape that area for 6 years.
