Longest Journey, The Easter Egg - Unseen Painting

In the Borderhouse living room, to the left of the pinboard, there is a small unmarked wall area that is a hot spot. Hovering the mouse over the area makes the cursor change to the "view item" cursor, with a caption "Painting" ("Gemälde" in german). Clicking on it makes April (the main character) walk not to that spot but to the right wall, which can not be seen by the player. She then says (translated from german) "A reprint of an early Lebowski", apparently describing a painting hanging on the wall. The painting can be briefly seen in a cut scene called "Vision in the living room" (german "Vision im Wohnzimmer"), which is only played if April has chosen to *not* work the evening shift at the cafe. The painting shows an abstract, comic-book-style rendition of a female head. The woman looks similar to Julianne Moore, who played the part of the artist Maude Lebowski in the movie "The Big Lebowski" (so the image might represent a self-portrait). Both the game and the movie are of 1998 vintage.
