They were part of the same campaign.
Step-by-step explanation:
Both posters are showing women who are determined to be defensive in the time where they can use their role to change a way they are seen. They were seen as housewives and in the 20th century, they get a job and work in defense industries and civilian service. Publicity campaigns used these posters to emphasize the women who now have a job. They were in a better position due to work that enables them not only salary but such a role of women who are fighting for their right to work.
