One of this year's Alex Award winners, The Scrapbook of Frankie Pratt by Caroline Preston is recommended by teen librarian Kathleen at Mukilteo.
Here's the publisher description:
"For her graduation from high school in 1920, Frankie Pratt receives a scrapbook and her father's old Corona typewriter. Despite Frankie's dreams of becoming a writer, she must forgo a college scholarship to help her widowed mother. But when a mysterious Captain James sweeps her off her feet, her mother finds a way to protect Frankie from the less-than-noble intentions of her unsuitable beau. Through a kaleidoscopic array of vintage postcards, letters, magazine ads, ticket stubs, catalog pages, fabric swatches, candy wrappers, fashion spreads, menus, and more, we meet and follow Frankie on her journey in search of success and love."
