Wow....I have the last Kubicki that Phil was building when he died. He also signed his name and dated the pocket.
So, is it worth tens of thousands $$ ??
A friend of mine owns the only Thunderbird that Leo ever built, as a custom order/favor for him.
Even has a custom graphic paintjob. A Leo one-off should be worth bucks. Even has a photo of him with Leo handing it to him.
