1983 Myojo Noodles Mechanical Cards

I love the odd-ball Japanese non-sports cards from the 1970s and especially these 1983 Myojo Noodles Mechanical Cards called Myojo Meka Kado (明星メカ　カード).  These cards came affixed to the top of a bowl of instant noodles.  I wish I could find a picture, but was unable to come across one in my internet search.  There are six 30-card series that I know of: World Classic Cars, World Motorcycles, World Ships, World Jets, Space/NASA, and Star Wars.  For those that collect the Star Wars cards, expect to pay upwards of $30-$40 per card...it'll be in the thousands for sure to complete the set.  For the other ones, they are fairly cheap when they hit the market...~$5 each, but they rarely hit the market in quantity.  In fact, the Star Wars set is the easiest to find (it might explain why they are more expensive) and the Space/NASA sets are almost impossible to find.  The cards measure 2.25" x 3.5" and are printed on thick cardboard.  I hope to pick up a few more of these now and then and I am not sure I am ever going to complete a set.  Here are a few examples of the Classic Cars, Motorcycles, and Ships sets.
