Your favorite birds are sure to be pictured in this wonderful collection of Popular Backyard Wild Birds of North America. This 1000 piece puzzle, illustrated by Catherine McClung, is labeled with each bird's common and scientific names. Cobble Hill puzzles are manufactured using the finest inks, premium grade blue board, linen paper, and the most endearing images. Our puzzles feature interesting random-shaped pieces - which are a departure from the more traditional predictable pieces found in most puzzles. No two pieces are alike. We also include a handy poster, making it easier for multiple people to work on the puzzle at the same time. We use quality linen print paper that gives the puzzle a luxurious look and feel. Not only does it look elegant, but it also works to reduce the glare by dispersing the light across the cross hatches much better than a smooth paper finish. We're environmentally friendly in that we use vegetable-based inks, and the cardboard is made from recycled material. Puzzles are sealed in shrink wrap. The box is thick and sturdy, so it can stand the test of time. The Cobble Hill Puzzle Company was founded in 2005 with a desire to bring quality puzzles with a loving, whimsical, and nostalgic feel to jigsaw puzzle enthusiasts and novices.
