Does anyone out there have any info/pictures of the BLVD signs of the 50-60's. Supposedly there were Brown Boulevard signs, but I can only locate pictures of the Yellow ones. Were thes signs the same one's with bent edges and just painted brown or were they flat? I know they were under park district control, but I still can't locate any info. I have one person who says the sign at AUgusta Blvd and Pulaski was brown in the 60's.
