A vertically oriented Phish New Year's Eve 98/99 concert poster is centrally depicted, mounted on a light-colored wall within an interior room. The poster features a stylized humanoid figure with large, upward-curving horns and a pointed tail, rendered as a dark silhouette. The figure is set against a cosmic background featuring pink and orange planets, stars, and swirling bands of color. Text on the poster identifies the event as "New Year's Eve 98/99" and lists the dates "DEC. 28, 29, 30, 31" with the venue "MADISON SQUARE GARDEN NY, NY." To the left of the poster, a dark, rectangular wall-mounted electrical switch or dimmer, characterized by vertical ridges, is visible. The scene is illuminated by a distinct purple ambient light, casting a glow on the wall and elements within the image. A light-colored horizontal trim is present on the wall below the poster. The exact location within the city of Winooski, United States of America, cannot be determined from the provided image.
