Did you get it right?
This 1950s church bulletin-printing corner shows a mimeograph tray, paper stacks, ink bottle, old stapler, hand-cut notices, and a wooden chair. Two office supplies do not fit.

The Answer
The correct answer is: The peel-and-stick correction-tape strip and the molded plastic staple-remover cap near the old stapler are the two mistakes..
Here is why
- The mimeograph tray, paper stacks, ink bottle, and old stapler fit the setting.
- Check the small office supplies around the paper and stapler.
- The correction-tape strip and plastic cap are the modern clues.
Why people miss it
Bulletin corners are full of white paper scraps and office tools, so a modern strip can look like another slip of paper.
