From the Lawrence Daily Journal-World for Sept. 25, 1972:

It had recently been discovered that only 93 of the 630 stop signs in the city of Lawrence were legally binding, that is, backed by a specific ordinance. Prior to 1967 it had been unnecessary for the city commission to take formal action in the placement of stop signs, and the majority of the signs had been placed before that year. However, the city attorney had advised commissioners that the informally-placed signs could be regarded as legally questionable. A survey of all stop signs having been taken, the list was to be considered at tonight’s city commission meeting and an ordinance suggested for emergency adoption. Also on the commission’s agenda was the annexation of a 10-acre tract west of the Santa Fe Industrial Park at the request of the Gustin-Bacon company, the construction of whose facility on the tract was already under way.
