Advertised in Beyer Band 288 (1934) on page 5.
Note: There is a Schwabe-Beyer Strickschrift with the same number - Schwabe-Beyer Strickschrift 70 639 - but that is for a different pattern entirely - Federblüte
Also Note: when Beyer 288 was reprinted as Beyer Bunte Reihe Band 2007 (1950), the advertisement for this send-away pattern was replaced by one for Agnes instead.
