I recently moved some books. There is a possibility that the condition of the books has changed slightly during the move. Please ask for a condition check before purchasing. Theory of Oligopoly: A Purely Theoretical Approach by Koji Okuguchi, Sobunsha (1/1/1971) 142 pages #RiverEastBookshop The slipcase is included, but it is considerably yellowed. The inside is slightly sun-tanned but relatively clean. However, a part of the endpaper has been cut out. The endpapers are generally reddish-brown. As this is a used book, there are yellowing, scratches, stains, and dirt. Please consider purchasing with the understanding of these conditions. Shipping may take 2 to 4 days. Please understand. #UsedBooks #Economics #TheoryOfOligopoly
