If the reproduction of this photo appears grainy and the colors slightly off, that is because it was made in 1956 — of early Port Royal. Gordon Pass would be off the bottom left corner; mangroves of Keewaydin Island are at lower right. Daily News reader Sheila Varnum said her sister, Pat Barnes, in High Falls, N.Y., spied the print at a street fair. A sticker on a plastic sleeve says "1956 Naples FL $9.00.'' Look closely to see the wood and rock groins that were early methods of beach renourishment; some fragments remain to this day.
