Hello Fernando, it is a pleasure to greet you again, good friend, I have been making these old cars for a long time, most of them are made of cardboard, I even made the first one with toilet paper cardboard and it turned out very well. In reality, patience and, above all, "creativity" are important for this job. Thanks for admiring my car collection. If you have a special car, send me the model so I can try to make it. Greetings. I will soon return to the instruments.
