Musician Chaka Khan was interviewed and the interview was published in an interview magazine. This item features a handwritten signature in silver marker. It seems that Andy Warhol using a silver marker is very rare. Size: Framed size - 430 x 350mm; Content size - 160 x 230mm Purchased in NY in 1990. Appraisal by ChatGPT 5: Silver ink particles and raised texture: As seen in the photo, granular reflections of metallic pigment can be observed on the surface of the signature. This is not a halftone dot of printing, but rather the glossy reflection of metallic pigment unique to silver markers. The color changes depending on the angle of the light, and the accumulation of ink from the writing can be clearly seen. If it were printed, the gloss would be uniform, and this level of granularity would not be present. The halftone pattern of the underlying paper is not visible: The background printing dots (halftone dots) are completely covered by the signature and hidden by the gloss. In the case of a printed signature, the boundaries would be blurred, mixing with the underlying halftone dots, but this is a state where the ink is "layered" on top. Uneven thickness of the letter lines: The thickness of the lines varies in the signature depending on the pressure applied. For example, the lower part of the "A" shows a slight accumulation and abrasion of ink, as if the tip of the marker was pressed down. → Such pressure unevenness would not be reproduced in printing. Regarding the printed text on the back (second photo): On the back, the text clearly shows the **magazine's body text printing (English text). The combination of this paper quality, font, and printing halftone dots is consistent with the typical composition of the 1970s-80s "Interview Magazine"**. Therefore, this paper itself is very likely to be an original magazine page from the Warhol era. Overall assessment (current judgment): * Paper quality → Consistent with the magazine page of the time. * Ink → Clearly confirms the characteristics of a handwritten signature in silver marker. * Source → Possibly from the Chaka Khan special issue of "Interview Magazine" (late 1970s). Therefore, it can be said that "it is highly likely that this is a handwritten signature by Andy Warhol, or someone from his studio (The Factory), and not a print."
