-inspired Music Hall section of the
Kansas City Municipal Auditorium. Heinlein came with an alarm clock, put it on his center stage podium, and spoke casually until his preset time period ended with the alarm going off. Heinlein was previously the Guest of Honor at the
3rd Worldcon (1941) and the
19th Worldcon (1961). He remains the only science fiction writer honored three times by the annual World Science Fiction Convention. Heinlein attended many MidAmeriCon events, including a blood donation drive and later donor reception at the nearby Hotel Continental, one of the Worldcon's overflow hotels. Being someone with a very rare blood type, Heinlein had organized the blood drive and reception to honor those anonymous donors who had donated blood, saving lives during surgeries, including his own earlier in the decade.

Ladies and gentlemen, please welcome the 8th Wonder of the Science Fiction World, Mr. Bob Tucker". As Bob appeared from
stage left, a brass-and-glass Art Deco podium slowly rose from a recess in the center front stage floor. When the applause died down, toastmaster Bob Tucker began his opening remarks, some of them humorous. He then introduced the members of MidAmeriCon's Hugo Awards Committee to more applause and thereafter made various announcements. The Hugo Awards were then presented, interspaced with five special awards which had their own presenters.

Following a brief intermission after the Hugo Awards presentation, Guest of Honor Robert A. Heinlein was given a lengthy introduction by Tucker. After coming onstage to a huge round of applause, he gave his guest of honor address to the assembled audience. This was followed by Tucker's concluding remarks and the close of the ceremony.

powder layers with resin and a hardener. When cured, a low-luster clear outer finish was then applied. Each example featured a sculpted, just-hatched dragon (representing the fantasy genre) wrapped half-way around each ''round'' 4.5" tall base. The traditional 13" tall, four-finned Hugo rocket (representing science fiction) was John Millard's newer 1973 design; a dozen examples had been machined from billet aluminum stock and then finished with an overall semi-gloss clear outer coat. The flat top of each base had a 4-inch diameter, quarter-inch thick, sand-blasted aluminum "transition" disk that each rocket sat upon. The rocket and disc where then friction tightened to the base through its center using a long threaded bolt and nut; each base's round, flat bottom was then covered with adhesive-backed dark brown felt to hide the recessed attachment point. A curved black-and-silver engraved Hugo information plate was affixed by two screws to the front of each base (opposite the wrapped dragon). The overall base design concept was by convention chairman Ken Keller, with the final finished design and casting master sculpted by three-time Hugo Award-winning fan artist Tim Kirk (who went on to win his fourth Hugo in the same category that year).
