These two bright colored owl reading posters are 11" x 17". They will look great hanging above your classroom library (you can attach them back to back if you plan to hang them) or on any classroom or library wall.
Print on cardstock, a thicker paper, if possible. Laminate them for years of use. Many printers will print 11" x 17" size. If not, Office supply stores usually do it for $1 or less. Happy Reading!
