This great little piece of photoshop art is by Reece Ward (did the watermark give it away?). An R2 unit repair manual in the inimitable style of the famous Hayes car repair manuals. (your dad probably had one).
Reece is also responsible for this great t-shirt design in the style of the English Heritage plaques that are typically nailed to the wall of past homes of famous and historical people. In this case…the Doctor. “Time Lord & Traveller” Who died in 1408 before he was born in 2300.(via)
