During a visit to the Gold Star Museum at Camp Dodge, Polk County, Iowa, I found their library had thousands of registration cards from World War I. I scanned about 30 of them for names in my family tree (not necessarily related). I have not found these in any database, anywhere online.
So, for about the next year, I will be presenting them here.
Thomas J Hanlon was born in Exira, Iowa and was 29 years 10 months old when he was inducted at Des Moines, Polk County, Iowa on the 3rd of July, 1918. Thomas is living at the same address: 1527-33rd, Des Moines, Polk County, Iowa, as Edward Hanlon, who we talked about a month ago.'
I believe this is the FindAGrave Page for Thomas J Hanlon.
