Nothing at all to be ashamed of in either pics, mate!.
Thankfully, there are no pics of me down in trenches jointing cables with my wildly unkempt hair all over the place!.
I have considerably less hair these days (not going bald though) I just prefer the good old #2 haircut, although it is rather grey.
This is the thing of hindsight, no-one took pictures on work-sites back then, because no-one thought they would be that important.
These days, every man and his dog has a digital camera.
BTW, don't you folks laugh too hard about that wallpaper, I'm told with good authority, that them patterns are part of the new winter collection about to be released in Europe.
The 1960's are back!.
Just think yourselves lucky that (hopefully) we won't be seeing any of the prints from the 1980's again, I mean Fido-Dido wallpaper??.
