Two Mistakes at This Old Hotel Bell Desk: Answer

Did you get it right?

This hotel bell-desk puzzle shows a brass bell, key cubbies, postcards, luggage tags, a ledger, and travel paperwork. Two small handling details are too modern.

The Answer

The correct answer is: The modern plastic luggage-tag loop and the peel-and-stick address label backing are the two mistakes..

Here is why

1. The bell, key cubbies, postcards, paper tags, and ledger fit the old hotel desk.
2. The plastic luggage-tag loop is a modern material clue.
3. The peel-and-stick address label backing on the ledger corner is the second modern clue.

Why people miss it

A hotel desk is supposed to have many tags, labels, papers, and travel items, so the modern pieces do not jump out immediately.
