I'm WAY too young to remember Old Chicago, but from looking at these old commercials, it looks like it was an indoor type of amusement park, kind of like what Camp Snoopy or I think it's Nickelodeon Land at Mall of America. Am I right?

@Brian1978 - Well, they did air the same commercial that day (almost - see below) but the one posted here did come from an entirely new and undiscovered Bozo's Circus episode that I found, which aired on Wednesday, July 11th 1979.

By the way, the version of this ad that did air during Chicagofest interestingly has a slightly different opening title card - all in white versus the oscillating multi-color seen here. Take a look.

This was the second commercial during the first break of the special, "Bozo at Chicagofest" taking place on August 3rd, 1979. I will always think of it being after the commercial for Dispensa's Kiddie Kingdom.

Wow, old post! Anyway, that's Steve Vinovich ("Mannequin") as the hapless father in the Aunt Jemima ad.

I like that several minutes of the film was shown, even if it was just for the onscreen ID. After watching, I felt as if I actually earned that commercial break. :')

"So whaddya got Johnson?"

"A brand new gum named for something your bathwater comes out of!...and wait until you see the commercial I came up with!"

What? No MGM Lion here?

Felipe Rose (the Indian) scarily resembles the Twi'lek dancer from Return of the Jedi who's dumped into the Rancor pit by Jabba, the way he's moving around on stage with the headdress swinging behind him.

Matt Snell is famous for having scored the only Super Bowl touchdown in NY Jets history, in their 16-7 win over the Colts in 1968.

Wow, that looks...gross. No wonder it didn't stay on the market for very long.

I'm almost positive that's Eddie Deezen as the groom; his face is a giveaway but I couldn't find any pictures of him with that hair. This would've been a year after he appeared in Grease.
