Sc.17, with SPECIMEN overprint in blue, mint without gum, very fine quality! (Image)

Large number of old stamps (I estimate several hundreds), the quality is mixed (some with defects, most seem of fine to very fine quality), COMPLETELY UNCHECKED, accumulated by an old collector over 60 years ago, it possibly includes scarce stamps, rare cancels, etc., GOOD OPPORTUNITY!! ATTENTION: please view ALL the photos of the lot, because all the stamps have been scanned (Image)
