giftshop | The Cryptographer

Location: Museum Gift Shop

You enter the gift shop hoping there is still a chance of finding Dr. Goldwater. You show her picture to the clerk, and she remembers her clearly, because she spent a long time playing with the paint-by-numbers tablet, then spent even more time looking through all the postcards, and then didn't even buy anything! The sales clerk seemed quite annoyed. But this may mean that Dr. Goldwater left you another clue. It's definitely worth checking out!

Hints

Hint #1

Dr. Goldwater spent time at all three postcard bins and the digital paint-by-numbers tablet. They may be related, somehow.

Hint #2

The paint-by-numbers tablet indicates that three of the puzzles have been edited by someone. They may not operate as expected.

Hint #3

It seems like some of the postcards were misplaced. Goldwater may have swapped them around for a reason.

Hint #4

Each of the postcards has an inventory tag and a catalog number. These numbers may help understand how to use the paint-by-numbers tablet.

Hint #5

The three misplaced postcards have the following inventory tags:
* 21D
* 65C
* 63B

Hint #6

Each of the paint-by-numbers demos is labeled by a letter (A, B, C, D). The letters in the inventory tag point to a specific demo.

Hint #7

The numbers in the inventory tags correspond to numbers in the paint-by-numbers demo.

Hint #8

The catalog number (after the painting title) also points to part of the demo.

Hint #9

On puzzle B, the numbers 6 & 3 should be painted in with color 7.

Hint #10

Demo B reveals three letters.

Hint #11

Demo C reveals four letters.

Hint #12

Demo D reveals four letters.

Hint #13

The letters in each demo are their own anagram. The result of all three demos is a 3-word phrase.

Hint #14

Putting the letters from each puzzle in the correct order reveals the phrase "The Book Nook". Search for The Book Nook on the New Hyperion Destination Finder map.

Answer

The numerical part of the address is 4500.
