New Year's Restoration

Here is my recent attempt to restore an old, slightly damaged illustration I did ages ago ... not a simple feat, considering that I no longer have the original photograph on which I based this illustration. This still needs a bit of work, but I'll post it anyhow ...

(Because the question was raised, I'll answer here that yes- these are real motorcycles- they are Moto Guzzis http://www.motoguzzi-us.com/intromuseo.asp?lin=eng, http://www.motoguzzi-us.com/storia/storia1.asp?lin=eng.)
