Spoiler!
1) You can ignore the black background, the symbol at the top, and the adornments around each of the five white rectangles as irrelevant to the solution. All that matters here is the 5 white rectangles and their positioning on the page.
Spoiler!
2) To solve this puzzle, you will need this page and the one right behind it (puzzle 36). Notice how large the letters are in the caption for puzzle 36? And the text is (not coincidentally) positioned right behind where the white rectangles are in puzzle 35.
Spoiler!
And the solution:3) Hold the pages for 35 and 36 tight together, and then hold (only) those two up to a bright light so you can see certain letters from the text of puzzle 36 shine through the rectangles of puzzle 35
Spoiler!
4) The letters-- from top to bottom and left to right-- spell 'relic'
