Final answer:
Visual puns in Northwest Coast formline design are created by using clever imagery and symbolism to convey multiple meanings. Examples include incorporating elements that resemble other objects or combining different elements to create new meanings.
Step-by-step explanation:
Visual puns in Northwest Coast formline design are created through the use of clever imagery and symbolism. These puns rely on the viewer's ability to interpret multiple meanings from a single design. For example, a salmon design may incorporate elements that resemble a tree to create a pun on the phrase 'fish in a tree,' which signifies something impossible or unlikely.
Another way visual puns are created is by combining different elements to create a new meaning. For instance, a design may combine elements of a raven and a fish to represent the phrase 'raven-fish,' which is a play on the word 'ravenous,' meaning hungry.
The use of visual puns adds depth and complexity to Northwest Coast formline design, allowing artists to convey multiple layers of meaning within their work.
