After years of research, sketching, traveling, and designing, Anderson Design Group put together this comprehensive collection of poster designs for each of the 63 major National Parks. • 18” wide x 24” tall. • Made with 80-point blue board, which creates a thicker puzzle piece with a more solid "hand". • Fun facts are listed on the back and inner sides of boxes. Even tho it’s only 500 pieces, it’s a fun & challenging puzzle!
