The Bloomsbury design gurus of Present & Correct just posted this c. 1982 invitation Cy Twombly made for his fifth—and last—solo show at Galerie Yvon Lambert.
The galerie was near the Pompidou, on Rue du Grenier-Saint-Lazare, which puts me three letters closer to a collaged greg.org watermark in Twombly’s handwriting. Although I will keep searching for less jagged examples that don’t look like Twombly wrote them on his lap while riding the Métro.
