For instance, Susie Seller has a Simplicity pattern listed which she describes as from the 70s. When Simplicity stopped placing the copyright date on the inside of their directions sheet, there was a gap of a few years before they started putting it on the pattern sleeve. Since Susie Seller's pattern has no date on the directions, it is likely from the late 50s to early 60s, or nearly 20 years older than she thought. The combination of letters and numbers hold the clue to the approximate date.
