all three cover contain letters,in them they discuss interviews,publicity budgets and the prospect of launching a us version,as well as recent appointments made by cinemonde including who theyve just hired,

i think lory was appointed as a hollywood interveiwer and copies of the magazine make reference to him being the author of some interviews,two are signed by gaston Theirry,the third I think by jean michael pages,

also mentioned are m.mounier ,ramon andrews,larry d wilson and henry didot as being appointed by the magazine

i know that the cinemonde magazine is quite collectable and early copies can be worth a bit,so would these have any real value associated with them
