Von dem heiligen Sacrament ein hübsch Lied : in der Brieffweyss Regenpogen Thon
This is a 1523 German broadside song sheet, printed in Strasbourg by Matthias Schürer for lay readers who sang it to a familiar tune, and its title names the melody as the Regenbogen tune. The woodcut at its head shows a priest elevating the host before kneeling lay figures, in a stiff, bold block style a designer could borrow for devotional or protest posters.
