The title photo is of the SPRO/John Crews' Little John Baby DD60 and a shad baitfish. This Clear Lake California shad/baitfish is typical and representative of shad all across the waters of North America, and so is the Little John Baby DD60.
Two concepts that should always occur when you want to fool a fish; illusion and realism.
Illusion = something that is or is likely to be incorrectly perceived or interpreted by the senses. A deceptive appearance or impression, misconception, false impression.
Realism = the quality of representing a thing, or situation accurately or in a way that is true to life.
