This is still-sealed, paper-wrapped "Fels-Naptha" Heavy Duty Laundry Bar Soap made by the Dial Corporation, Phoenix, Arizona. - Net wt. 6 1/2 oz (184 g) - Laundry soap in bar form needed to be "grated" prior to use.
Circa mid to late 1960's based on the packaging and the addition of the UPC bar code on the reverse. Although UPC codes began appearing on some products as early as 1966, they were mainly for internal company usage as the first store market scanner to read them wasn't installed until 1974.
