The Past Through Tomorrow by Robert A. Heinlein

This is a hardcover edition of Robert A. Heinlein's science fiction short story collection, 'The Past Through Tomorrow'. The book features a dark purple or navy blue textured cloth or paperboard binding. The spine is clearly visible, featuring white sans-serif block lettering for both the title and the author's name. A thin horizontal white line separates the author from the title. The construction appears to be a standard trade hardcover format from the late 20th century, likely the 1967 G.P. Putnam's Sons edition or a subsequent printing. Regarding physical condition, there is visible shelf wear particularly along the top edge of the spine, where slight fraying and color loss are evident. Some white dust or particulate matter is visible on the top edges of the cover. The pages, visible at the side, show slight tanning consistent with age. This volume contains Heinlein's iconic 'Future History' stories and is considered a seminal work in the Golden Age of Science Fiction. The craftsmanship is utilitarian but durable, typical of mid-to-late century major publishing house mass-market hardbacks.
