Amateur crooner wannabe who wishes he could be like famous radio star Rank Finatra. From the funny animal comic book Jack-in-the-Box Comics #11 (October 1946).
His jerk "friends" Philly and Bert convince him his sour notes are sweet music and to sing at the local amateur night. Then they buy a lot of produce to throw at him during his performance. Their "joke" backfires when the next day Horace opens a lucrative fruit and vegetable stand.
Horace sings "Its Only A Cardboard Moon," a parody of the 1933 song "It's Only a Paper Moon."
