From the Lawrence Daily Journal-World for Aug. 5, 1971:

Got milk? Students in the Lawrence school district were to continue receiving their lunchtime milk in paper half-pint cartons for the immediate future, in spite of objections from some school board members. Earlier, members had asked staff to investigate the possibility of using returnable containers or a bulk serving method to cut down on trash and resulting pollution. The cost of installation of bulk milk dispensers was estimated at $6,750 for the 27 Lawrence school buildings, and there was a lack of returnable glass milk bottles, so the district had decided to continue with the paper cartons. Three dairies had bid on supplying the year’s milk, with Lawrence’s All-Star Dairy receiving the contract at 5.5 cents per half-pint. Meyer Dairy of Basehor and Beatrice Foods of Topeka had also bid on the milk contract.
