2nd appearance of Kandor; see Action #242 for debut. Kandor is referred to only as a "Kryptonian city." It is depicted as a very wide-necked bottle like the Swan-drawn newspaper strip version, not the Plastino narrow-necked comic magazine version.
The illustration at the top of the letter column is taken from the splash panel of the Superman story in Action Comics #241. This illustration appears at the top of the letter columns in Action Comics #245-271 and Superman #124-145.
