What material is the treasure map's thin paper described as?

• A. Onionskin
• B. Parchment
• C. Vellum
• D. Rice paper

Answer: (A)

Onionskin paper captures the idea of a treasure map that feels delicate and almost ghostly. It’s extremely thin and semi-translucent, so the map can be seen through and could tear easily—traits that suit secret messages and adventurous lore. Parchment and vellum come from animal skins and are much thicker and sturdier, giving a sense of durability rather than fragility. Rice paper is thin too, but the term onionskin has long been tied to this ultra-fine, translucent sheet used for drafts and covert documents, making it the best fit for describing the map.
