The Ultimate Guide to Collectible Lego Sets: Identification and Price Guide Paperback - 2015

Ed Maciorowski is the co-founder and co-owner of BrickPicker.com. He has been a LEGO collector since 1973, when his parents gave him his first set (710 Wrecker with Car). Ed is now an investor as well, with over 6,000 sets in his collection and a current market value well into the six figures. He and his brother, Jeff, got the idea to create the online LEGO price and investing guide after Ed discovered that a 10179 Millennium Falcon set he bought for $399 was selling for $800-$1,200 on eBay two years later. The price for that set is now nearly $4,000. Ed also is a regular contributor in the LEGO-themed magazine, BLOCKS.

Jeff Maciorowski is the co-founder and co-owner of BrickPicker.com. He is a senior website engineer for a $40 million market research company and specializes in multiple web technologies, including Cold Fusion, jQuery, Oracle, and mySQL. Jeff built Brickpicker.com from the ground up and it is now the third busiest LEGO-themed website in the world that attracts over five million visitors annually. The site has been featured in the USA Today and other digital media outlets (BBC.com, Wired.com). Jeff is also the creator of the recently launched BrickClassifeds.com website, a cost-effective secondary LEGO marketplace.
