VENEZUELA - 1850's-1990's EX DEALERS STOCK BOOKS A mostly used range presented chronologically on old manilla stock pages, in two, non philatelic three ring binders (one of postal issues, one of  Airs & back of the book). An extensive range with many complete sets, with each issue identified by Scott Catalogue number with shade & postmark interest, unchecked in any detail, but at a glance, light duplication seen throughout, dotted with mint & better issues with 19th Century seen to Bolivar values plus 1866 ½r strip of three inc a Tete Bêche, extensive Air Post ranges & a selection of Officials, etc. Much of interest here! (guess 3500+ stamps)
