Close-up photographs of 10 beautiful tulips in a rainbow of colors grace this new USPS booklet of 20 stamps. One blossom fills almost the entire frame of each stamp, with just the top of a stem peeking out from underneath. Each fall, millions of gardeners bury bulbs in the earth, eagerly anticipating the rewards that springtime will bring. Months later, thick green leaves poke through the soil, soon revealing their treasure: Tulip blossoms in spectacular variety from prim to ostentatious. Since Dutch immigrants brought tulip bulbs to North America hundreds of years ago, the flower has become a dazzling part of our landscape. Art director Greg Breeding designed the stamps with existing photographs by Denise Ippolito.
