Should you somehow travel back in time to Joplin, 1925, and find yourself with a bag of dirty clothes, one option would be the Keystone Laundry, located at 410 Virginia Ave. Below is a receipt from the laundry from 1925. There’s more than a few items on the receipt that simply don’t come up in conversation anymore. To our knowledge, there’s no connection between the Keystone Laundry and the Keystone Hotel (located at 4th and Main).
