Small 3-D shadowbox of Times Square - Help!

An auction find, this work is of Times Square, NYC, and was fashioned by taking 5-6 of the same image, laying one down as a background, and building up various parts of the landscape by cutting out and fastening them to the image to make a great three dimensional effect. The frame measures 9" x 17" x 1", with the image around 13" x 4 5/8".
I can't decipher the signature. If anyone knows anything about this, and can help, please let me know.
