Question

jigsaw puzzle on topo sheet(50 words) ​

Answer 1

Answer:

Jigsaw puzzles were originally created by painting a picture on a flat, rectangular piece of wood, and then cutting that picture into small pieces. Despite it being called a jigsaw, a jigsaw was never actually used to cut it. John Spilsbury, a London cartographer and engraver, is credited with commercializing jigsaw puzzles around 1760.[1] Jigsaw puzzles have since come to be made primarily of cardboard.
