This pattern first appeared in 1941 in Beyer Band, 454.

After the war, this Strickschrift was advertised in Beyer Bunte Reihe Band, 2007 (1950) which was a reprint of Beyer Band 288 (1934), except for differences in the send-away patterns.

“Maiglöckchen” was advertised on page 13 of BBRB 2007 in place of “Ursula”, which had been the send-away pattern in the original Beyer 288.

So while the pattern dates to 1941, the Strickschrift appears to date from ~1950.
