// Condition analysis
⚠ AI-Estimated / Approximate Condition Profile
This pre-1977 book has only one edition, so no direct/newsstand distinction applies. Visible defects include noticeable spine stress with wear along the top and bottom spine edges, a vertical crease running through the lower left cover, corner wear at the bottom left with slight blunting, and general handling wear/soiling across the surface. The book is housed in a protective sleeve which adds slight glare but does not obscure major flaws; interior and back cover were not assessed.
