Work on this sheet, the third in the series, began like that on the preceding one in April, 1971. Its original stemmed from a profound personal crisis, and to its title (630) Yellow houses Hundertwasser added the word Jealousy. Closed windows, the girl's face, tears. Everything emphasizes the picture's subject. The print's title, formulated years later, still echoes the emotion.

The objective of the Dietz Offizin, to produce facsimiles barely distinguishable from their originals, ensured meticulous precision and subtlest craftsmanship. Thanks to the artist's direct collaboration, the Offizin's success was in this instance altogether outstanding. Hundertwasser's share was the production of about ten monochrome pictorial creations on transparent foils. With the most up-to-date machines, great energy and ingenuity were devoted to following up artistic potentialities, ideas, and flights of fancy. Their realization brought about quite exceptional results. The phosphorescent colors glisten in the dark, and in unlit rooms they produce highly individual impressions. Thanks to the imprinting of variously aligned relief grids, "the metallic cupolas sparkle in a mysterious kind of space".   -Walter Koschatzky, Hundertwasser: The Complete Graphic Work
