Landships II

Greetings all! I just joined the forum, and I thought I'd introduce myself. I'm a card modeller, and have a particular interest in WWI armored vehicles. I'm hoping to tap into the vast reservoir of knowledge here to improve my modelling, and hopefully contribute a little myself. I'm currently building an Ehrhardt E-V/4 in paper. I found the black and white file during a google image search, and colored and weathered it using Photoshop. I'm hoping someone here might know who is responsible for the B&W. If any of you would like to see the Ehrhardt (or other of my WWI armored cars), just say the word.
