Victorian vs Traditional Jigsaw Puzzles
Victorian-cut puzzles feature unique-shaped pieces and whimsies - every piece is different. This type of cut is popular for wooden jigsaw puzzles. Traditional-cut puzzles featured the standard ribbon cutting jigsaw puzzle pieces, with only a few shape variations of pegs and holes. See the examples below from Peaceful Wooden Puzzles.
