This was a poster produced in 1917 in America. Obviously aimed at women, this poster is trying to persuade women of all ages to provide for the war.  The women with the shield may suggest that she's the one that has the power over the other.  The other might be her daughter.  She is also placing a sword in her hand. I think this may mean she's giving her authority and a particular identity.  The sword reads 'Service' on it. I think this means as an object such as a sword resembles power and also a gift. The sword and the shield the women behind her is carrying are matching.  So maybe she's sharing her own experience of what she has in the war her too.  Also she looks much higher up than the other girl.  The clothes she's wearing may say that she's quite powerful and/or very respected.  Her clothes look much more royal/posh and flow down her.  She also looks like she runs the 'State & National councils of Defense' which is written on her shield.  I think in WW1, women would of looked at this poster at taken notice of persuasion to serve for their country.  The clothes the younger girl is wearing suggests to me personally that she's a day to day women.    The typeface is placed at the top of the poster but for me, this wasn't what i was first drawn to.  Also the style that the title of 'Women Your Country Needs You' is written in is quite playful.  I think that the women's head has been made to separate the words 'Needs' and 'You' to emphasis a personal message impact on the viewer.   This would and proberly did result in more women listening to the message of this poster.  In the background there are soldiers
