Did you get it right?
The engraving room hides a graver, button, postage stamp, and walrus.

The Answer
The correct answer is: the graver, button, postage stamp, and walrus suggested by engraving-line fragments.
Here is why
- The graver blends into the tool tray.
- The button sits by the apron at right.
- The postage stamp rests on the papers near the center.
- The walrus is suggested by separated tusk, shadow, plate-gap, and cable fragments on the upper-right workstation.
Why people miss it
The engraving lines and shadows make the walrus fair only once you know where to look.
