Maxie's Night Club
23rd Ave. and 19th Street
East Moline, IL
Owned by Max O'Klock

info is from a news clipping regarding a fire at this location in 1950.

I believe this is more accurate than the recollections of a niece. Your
"Max & Dan" theory makes sense. Max is still alive, or was a year ago anyway,
so perhaps we can ask him about the "D".
