Mystery of the New Lyric

I've known for decades that one of Ayn Rand's Chicago relatives owned a movie theater. Today I read, in an article, based on archival research done by Shoshana Milgram, that this movie theater was key to Rand's getting out of Russia.

One of the Portnoys’ children, Sarah, owned a movie theatre, which made it easier to obtain Communist Party permission to study film in America, as Vladimir Lenin had designated cinema as the most important art.

And where in Chicago was the theater?

Thanks to a movie diary that young Rand kept, it’s clear that she saw many movies at Sarah’s theater, known as the New Lyric in 1926 and located on West 57th Street near South Halsted.

But I have found other evidence online, at a site devoted to old movie theaters, that the New Lyric was actually located on West 47th, not 57th.

Open since at least 1913, originally known as the Colleen Theater, this small house, first operated as a nickelodeon by Hyman Lieberthal, stood on 47th Street at Emerald Avenue in the Canaryville neighborhood.

By the early-1920’s, the theater was called the New Lyric Theater, and by the late-1940’s, had been renamed the Mid-Town Theater. The former theater most recently housed a bar, but has since been razed along with most of the block it stood on and replaced by a condominium building.

The address given at the above site, 718 W. 47th, is indeed near Halsted. And 47th is a commercial street, whereas 57th is a residential street, so it seems a lot more likely to have been on 47th.

Just to add to the confusion, however, another online compilation of movie houses puts the Midtown Theater at 718 WEST 47th, but puts the New Lyric at 718 EAST 47th.

I suppose I could go and look up property records at the County Clerk's office. Or maybe look at the movie ads in old newspapers from the time when I know Rand was in Chi-town.

Maybe the article just reflected a typo. Maybe I am way over-researching this.

I don't mean to grouse,
but where exactly was this movie house?
