A supporter of equal rights for women.
Explanation:
Elmer Andrews Bushnell was the illustrator of "the sky is now her limit", in the year 1960, who depicts a ladder of symbolization of norms for gender equality. She is a great supporter of equal rights for women.
This illustration was created right after when women had their suffrage rights, this piece helped the women to go beyond for the rights for equality and presidency.
The bottom two rungs are "slavery" and "house drudgery", and slowly followed up by the careers for women, soon there is equal suffrage and then there is "Presidency". An illustration from an ordinary supporter was more like a level up for the rest of the women community to move forward.
