Not exactly high art but if you are looking for something fun and “saucy” to fill a space on your wall, then Amazon seller Stick It on Your Wall have a good selection of Retro Glamour Pin-Up Girl Posters.
They all feature illustrations of 1950s glamour girls with varying degrees of sauciness, dressed in swimwear, eveningwear or costumes. The posters measure 30cm by 40cm and cost just £5.99 each. They are sold unframed, so would benefit from being put in a frame before putting on your wall.
They can be bought online via Amazon.
