This s an illustration I did a while ago but it seemed to fit with this topic so well I thought I'd use it.
This was another of the old derelict things I like so much and another chance to do some weathered texturing.
I saw a documentary recently in which they said that there are still lots of old tanks from WWII abandoned and rusting away in various places round the world. Recently though people have cottoned on to the fact that they are worth a lot of money so they are now being recovered for museums and for restoration.
Personally I think they can say more being left where they are.
