WWII era 'Blinky Bill' birthday card

World War Two era birthday card featuring the Dorothy Wall character, koala 'Blinky Bill'.
The front cover is a bright blue kit bag with a cream coloured tag suspended with red, white and blue string, which reads 'Pack up your troubles in your old kit bag and..." in red and black lettering.
The kit bag opens to reveal the words 'Smile!, Smile!, Smile!' also printed on a cream coloured tag suspended with string from the top.
On the opposing page, there are 4 jokes printed in black lower case lettering on a cream background. These are made to look like newspaper cuttings and are positioned on differing angles.
There are a further two sets of pages, each with 4 jokes, making five pages in total.
At the upper left of the final page is the text 'Happy Birthday' in red letters, under which is an inscription in faded black ink which reads 'To Nan from Ede, Mary, Betty & Dick with love'.
The depiction of 'Blinky Bill' appears below this on the lower right of the kit bag on the final page. He is wearing a slouch hat with a chin strap and a rising sun badge on the side, and a tunic and leggings. He appears to be marching from right to left.
A red, white and blue stripe extends vertically down the right hand side of the card, while a small section of the same stripes extend from the top on the left to the top of the kit bag.
The back cover of the card is plain with the exception of the publisher's symbol - two triangles with the top one inverted creating an hourglass image, with the letters 'J' and 'S' either side of the narrowest point.
