PENNSYLVANIA RAILROAD 100 Years of Progress and similar items

100 YEARS OF PROGRESS IN MODERN RAILROADING PENNSYLVANIA RAILROAD (1934) illustrated ten-page fold-open brochure MY GRADING SYSTEM I try to be fair and honest in my grading, and make every attempt to mention loose pages, stains, tears, binding damage, etc. Sometimes I find that an item falls between two grades, in which case I will list it with a two-grade scale. NEAR MINT - MINT: I rarely use these grades, except when an item is in truly exceptional condition. VERY FINE: very nice with virtually no major defects. FINE+: an even nicer copy, with minimal obvious defects. FINE: a nice copy, flat with minor creases; may have some spine stress, but no prominent defects. FINE-: better than VG+ but just a bit short of what I would consider Fine. VERY GOOD+: most of the items I list fall into this grade; a typical read item with obvious defects as noted. VERY GOOD: fairly well-read with an accumulation of tears and defects as noted; may be heavily creased or spine-rolled. GOOD: a complete but heavily-read item; may be missing pieces of covers, loose covers, rolled spine or other noted damage. FAIR: a rough item, with many defects including tears, missing pieces, water damage, spine wear, etc. POOR: no missing pages unless noted, but otherwise a pretty trashed item; almost any and every damage may be present.
