Ca.1960-70 Ruana Bowie Knives Mailer,9" x 14" with both sides shown.There is no date but the prices and use of Chrome Alloy steel for the blade material lead me to late 1960's -70's.The Bowies range in price from $22.50 -$42.50. Excellent Condition with creases where folded to fit an envelope,edge bumps and some text crossed out in ink
