Galerie Henneberg, Zürich ... : Auktion in München in der Galerie Helbing
An 1903 Munich auction catalogue from Hugo Helbing's gallery, listing the Henneberg collection of Zurich for dealers, collectors and bidders at the sale. The plates are halftone photographs of paintings—devotional heads with incised haloes, powdered-wig portraits in oval frames, a Dutch guardroom scene of plumed hats and satin sleeves—printed in warm sepia and grey with soft, low-contrast tone useful for muted backgrounds, portrait vignettes and period costume reference.
