The Cake is a Lie...or is it?
The ubiquitous Cake is spoken of frequently throughout Portal. You'll find Rattmann's drawings in his "hidden" dens where he frequently claim that the cake is a lie...but (SPOILER ALERT!!!) the ending of Portal shows the actual cake. This implies that GLaDOS really hid the cake really well for "Cake and Refreshments".
The wood is 4" square and 1/4" thick hard maple, cut by hand on a scroll saw. It's finished with 3 coats of a water-based polyurethane for water resistance, and backed with 1/8" thick cork painted to highlight the design - these deskorations can double as coasters! Hard maple wood grain is quite variable, so every deskoration is unique.
Be sure to order a stand so you can display your delicious slice of Cake - you can find the stands here: https://centuryartisans.com/products/deskoration-stands
