Negamco (originally Nemadji) has been around since the late 1950's. After an initial run of the Basketball game in 1959 the company merged with the Big League Manager company and for most of it's original run was distributed and produced in conjunction with that game. While the same company produced both games they marketed the Negamco series of games as the "little brother" to the Big League Manager series since they were simpler and less expensive games. To my knowledge the games were available only through mail order. The company stopped producing new season sets in the 1990s.
The digest is in VERY GOOD condition. It is 100% complete and shows typical handling wear. No stains or writing. Staples are still intact. It includes ratings for the then current Georgia Tech College Basketball team, BU and Univ of ND College Hockey teams, 1969 NBA and NFL Rookie ratings, and some Boxer ratings. It also includes a revised out chart for Negamco Baseball. Overall I would grade it a 5 on a 10 scale (see condition guide below).
MINT (10): I will only give this grade to brand new, unused items. NEAR MINT (9): Shows virtually no use. Seldom if ever played. Perhaps some very light handling creases to the instructions or other minor flaws with the game parts. Boxes will have only the slightest hint of shelf wear. EXCELLENT (7-8): The game has seen some use but it was obviously well taken care of. Game parts might have some light handling creases or other signs of careful use. Board might have just a hint of color loss or dented corners. Boxes will have light rubbing to the artwork or perhaps some minor dishing or a very light stain. VERY GOOD (5-6): The game was not especially well cared for but it still has faired pretty well. Game parts will show obvious use but nothing will be torn, badly stained or have any serious damage. Box may have some rubbing, light staining, dishing, 1 or 2 neatly split corners, minor writing and/or a few pieces of tape. No major structural damage and artwork will still be generally attractive. GOOD (3-4): Obviously no care was taken with the game but it is still playable as is. Game parts show considerable use but the game is complete with all parts in usable condition. Box may have staining, writing, split corners, dishing and/or other structural damage but it will be intact and still usable. POOR (1-2): Only suitable to fill a space in your collection. Game will be missing parts (these will be noted). Box will have serious damage and may be missing aprons or badly torn.
