This sale is for (4) vintage, 1980's era, Fisher-Price Construx, Action Building Systems. One set appears complete/unopened. The others appear possibly unused and at the very least near complete, if not fully complete. Lot consists of #586 Stellar Exploration Set, this set appears to have never been taken out of box. #6201 Cosmic Viper, #6021 CX21 Interceptor, #6311 Mobile Patrol. All sets look to have unused decals & paperwork. The three sets that were opened do appear to have most or all of their pieces. Original boxes have some storage wear, ie creases/dust small marks etc. Pieces have some dust, but do not appear to have ever been used or even put together, in fact we were told by original owner, he never put them together as he was more of a G.I. Joe kid. Selling AS-IS, we are not guaranteeing that sets are fully complete. Feel free to ask questions. Thanks!
