Below is a photo of one of the magnificent doorways to B. Altman on 34th Street in Manhattan, NY. My mother used to go there when she went into ‘the city’. B. Altman is defunct but, at the time the photograph was taken (circa 1990), the doors opened into one of the new (at the time) NY Public Libraries, one devoted to computer technology.
Below is my sketch. I remember the awning was ribbed with green; probably weathered copper sheeting. The ribs cast radial shadows beneath the covering.
I’m proud of this piece. However the shadow masking the details on the right side seems more like a gray mass. Perhaps the use of color and grayscale explains this.
