"Sig Fig" stands for "Signature Minifigure".
At the Lego company, all higher up employees who work at the headquarters, the set designers, developers, project managers, etc- all have "Lego business cards" that are actually Lego Minifigures with thier name and contact email on thier backs!
The Minifigs are often given hat/hair or other accessories to make them resemble thier human counterpart. This is such a cute idea that many of the Lego fan community caught on and started creating custom minifigs meant to resemble ourselves!
SJLUG believes in recognizing our members- and making it easier for us to connect (online and off)- and we love being able to get to know each other & to find each other's Lego social media accounts, contact info, sometimes websites or BrickLink stores for the other club members. To solve that we've created the useful member guide below! Take a moment to check out the SigFig faces of the South Jersey Lego User Group!
