A happy accident of misdirection took me past this lovely thing. Alschuler is probably best known for the London Garantee Building at Michigan and Wacker. I don’t know anything about the Kling Brothers, but I’m assuming this was a warehouse/factory of some kind. Nice incorporation of the Magen David in the logo. Side note: Alschuler worked for Dankmar Adler and designed the second synagogue for the KAM Isaiah Israel Temple in Hyde Park. The previous building was designed by Adler and Sullivan, which suffered a horrific fire back in 2006.
