Final answer:
The artworks discussed, such as 'Oh! Soldier' by Sarah Lucas, use unconventional materials to comment on gender and societal issues, while Soviet propaganda posters depict military might and ideological fervor.
Step-by-step explanation:
The discussion touches on various forms of visual art, encompassing sculpture and posters that convey complex social and historical themes. The works mentioned, like Oh! Soldier by Sarah Lucas, use items like nylon stockings and concrete to challenge gender perceptions and explore objectification. Another example is the 'Under the banner of Lenin, forward, to victory!' poster, which is a vivid portrayal of Soviet propaganda's celebration of military prowess during wartime, showcasing the might and determination of Soviet soldiers.
Such art pieces are not just reflective of the artists' creativity but also serve as commentary on the society and the period in which they were created, emphasizing themes of war, gender, and political ideology. The way that each piece of art manipulates materials and symbolism provides a rich field for analysis in the broader context of cultural studies and art history.
