digital, from memories of two originals – made when the original painted sketch with purple roads and the gold building was misplaced, and I needed a quick representation. Made in photoshop not many years ago – it is here rather than in the trash, as my memory reversed the two colors for the Philadelphia Museum of Arts and the bridge over the roads overlooking the Schuykill River, and I find this interesting – I could perhaps have made more sets of two color reversals for the project for various components.
