"Ein unvergessener Tag" (An Unforgettable Day) is an oil painting by German artist Georg Baselitz, created during a period when he was exploring expressionist figuration. The work exemplifies Baselitz's characteristic style of distorted, energetic brushwork and often features inverted or fragmented forms that challenge conventional representation. As with much of Baselitz's oeuvre, the painting reflects his engagement with German artistic traditions while asserting a distinctly contemporary sensibility through its gestural abstraction and emotional intensity.
