A list of state and provincial birds of the United States and Canada and…

A list of materials needed and methodology for "gyotaku" (fish rubbing) are provided. Originally developed in Japan and China during the early 1800's, the technique of fish printing has become popular in the United States during the last 10 years. Because good printing results depend on an understanding of fish anatomy, a chart is…
