Billiken Parade is an ongoing Chicago tradition started by the Chicago Defender, a prominent Black newspaper and it's a back-to-school parade. Historically politicians have marched in this parade primarily to be seen whether Republican or Democrat.
Recently I discovered a post at the Chicago GOP's official website and they share a link to an album of nine photos. They contains scenes of the parade and then other pics are of other GOP committeemen and GOP candidates for office. In fact one pic are of children holding up nail files for Republican state treasurer Dan Rutherford.
BTW, the pic above are of two GOP committemen Adam Robinson on the right and Percy Coleman on the left.
ALSO, in future I suggest the city's GOP hire a professional photographer to take more pictures of these events also identify who's who when they upland and save the mobile phone pics for a Twitter pic or a Facebook post.
