Thrilled to receive my copy of Arcade Materials: Blue, in which you will find my piece “U is for Head: an Alphabet Adventure!” (here printed as “U is for Head: an Alphabetic Collection”). This volume is the third of a trio of monographs on Walter Benjamin’s arcades project. My piece engages with convolute H. I consider the magic-alphabet quality of the practice of art collecting—as usual I am concerned with the perfect individuality and unintelligibility of each figure in such an alphabet. Purchase this volume or all three here.
