I did find a WWI Draft Registration Card for a David Prass of Minneapolis, born 1874. Just lists his occupation as "Clerk" though. Don't know if its the same guy.
Buzz--interesting! Often people in a town or city would mail letters to others and just use the word "City", but I have not seen that used with tokens. I believe it is probably from Minneapolis, but don't find the guy at that address. The numbering may have changed over the years, because that address now is a residential area. Please post it on tokencatalog and I will tip off the MN token cataloger to look at it and see if he can use his local resources to firm up the attribution.
