Handle & Dropkirk - by me at an unknown age

Clearing out under a bed back at Mum's house over Christmas 2015 we found a whole load of artwork, including Hev's work from art college and some comic strips by me that I've not seen for years. This was by far the earliest piece.

Though most work was from my late teens and student days, this one picture has survived, drawn and painted by me at an age I can't quite pin down. Because it references Randall and Hopkirk (which was on ITV from September 1969 to March 1970) and Star Trek (on BBC between July 1969 and December 1971) I'd say this is from 1970, making me 8 or 9 years old. However there was a 20,000 Leagues Under The Sea movie made by Disney in 1973, and I remember reading the comics version of it in Donald & Mickey comic, so if I'm referencing that, this would be from when I'm 11 years old. But I'd like to think I was better than this by then. We may never know.
