A New Interest...Time waster?

So I've been fooling around with typewriters. Seeing as the equipment is pretty well outdated by computers - anyone with any sense & who has anything serious to write will use a PC based word processing program that not only allows easy corrections & multiple copies but also a far more flexible layout process, the majority of people interested in typerwriters are either collectors or artists. Make that rather geeky artists.
I thought that given the age of the machines I was using, it might be fun to also give my copy an old, yellowed & dog-eared effect.
This is the result.
