I'm Going to be a Big Brother Secret Message Wooden Jigsaw This 30 piece wooden jigsaw is a great way to let you little one know that they are going to be a big brother, it comes in a drawstring bag & when they have made the jigsaw, they get to read the secret message. Please also see our other listings for Big Sister. Our jigsaws have been illustrated by a published UK illustrator who has produced work for Usborne & the Welsh Council for Books Each image is complimented with hand written text, which varies on each design & adds “personality” to each product.
