Baker Street – London Underground Sign - Art I have carefully created each part of this imaginary art poster in Photoshop and Corel Painter. The London Underground Map is a scanned image from an original map by the famous H.C. Beck. I have added period underground tickets, I hope that you will find them interesting.
