Some of the Lego Polybag Promotionals are very hard to find or are only given away as a promotion to help a company out. Or you missed a set yet want it! So what can we do? We can become COPY CATS or COPIERS and COPY the designed set. And LEGO makes it easy, they offer Building instructions on their site: http://service.lego.com/en-US/buildinginstructions/ and with their Pick-a-Brick option: http://shop.lego.com/en-US/Pick-A-Brick-ByTheme you are off and running! PLEASE NOTE: you can also send Lego a List of Parts Wanted and they will come back with a quote (this is good for parts not in Pick-a-Brick) and you again are on your way once they arrive. BUT beware you cannot get stickers or mini-figures that are licensed! And sometimes you'll need to do a color substitute as in the pendulum of the GRANDFATHER CLOCK and the ARSENAL wall that originally were light gray and dark stone gray! In that case modify! Here I re-posted my GREEN GOBLIN, I introduced: HAWKEYE'S ARSENAL, I re-posted my GRANDFATHER CLOCKS and I debut my ANDREA'S MARQUE. So once you see Hawkeye or Andrea again...YOU ARE NOT SEEING DOUBLE!
