I collected this pair of William Haskins stamps on my way to go vote at my polling place (the Pilgrim Congregational Church). Lansing had a city council and mayoral primary today. The stamps are in a pleasant little shady corridor on the south side of Prospect just east of Lathrop.
Unfortunately I have yet to find a dated William Haskins stamp, though there are a fair number of them sprinkled around this area, and I still don’t know anything about the contractor.
