There is something about pumpkins that says "autumn". The unlabeled version of our pumpkin poster would be good to give to young children to decorate as a jack'o'lantern with a black pen or paper.
Pumpkins are often associated with autumn and harvest time, as well as Halloween of course! Pumpkins are ready to be harvested once their shell has started to harden - the ones on our poster look perfect!
Carving pumpkins to make Jack O'Lanterns is a really fun part of Halloween. Maybe you could try copying one of the designs from the pumpkins on this poster? Or print out the poster for a Halloween display?
