I've seen several versions on Ebay. This one is nice because it's so big. I like one that has the Lotus logo on it, but it's smaller, plus the seller wants $7 for shipping in the US, which seems like a ripoff. Haven't decided what to get yet.
I've got two vinyl signs in my garage (did I mention that I moved and now have a garage?) that I got off ebay. They're both the soft vinyl type with grommets... one is black with a silver lotus ACBC logo, the other is white with green and yellow Lotus ACBC logo and LOTUS Motorsport on it. Nice big signs.
