My Fathers Day gift this year was the spectacular Lego Concorde model kit, an adult-level "toy" that, once built, results in a detailed model of the iconic Concorde supersonic airliner measuring 41.5 inches long by 17 inches wide!
I'm having a great time working on building the model, and have been astounded by the intricacy and detail provided (like the onboard lavatories seen here) - will post more photos of the completed effort!
