Vintage Mid 1970s Levis "redline"

   Selvedge is also known as 'redlines' or akaimimis which in japanese means 'red ears'.It is located on the inside of the outside seam of the jeans.  It indicates a pair of vintage or vintage reproduction Levi's.  Other details will have to be used in order to identify the jeans as vintage or reproductions.

 The first generation of Levis jeans made with the duck cloth do not contain redlines or bluelines.  They have whitelines or white ears.
