The Kyles of Bute form a narrow sea channel separating the northern end of the Isle of Bute from the Cowal peninsula in Argyll and Bute, on the Scottish mainland.   Surrounding hillsides are roughly wooded, and overlooked by rocky tops and areas of moorland.   This card, mailed in 1959, has its stamp and an unusually clear postmark.  A bit of handling shows on the front.  Grade: 2
