2002		K. Lucas ‘All my life I’ve wanted to be a Barrow Boy’ in Obfuscation News Apr. Issue 20 🌐 Now I have a one owner, one horsepower, low mileage, Iron Mike Blair. [No he is not the brother of A. Blair]. The Iron Mike has been adapted to have a Hat and Scarf Blair fitted so that the shafts fit into the arm rests and you sit in the Blair and drive and steer like our beloved Leader. Like him you will be in sole charge of your destiny. You can have it for a Tony.
