1957 Scout Jubilee Jamboree, Plain FDC, 2½d Stamp Only, World Scout Jubilee Jamboree Sutton Coldfield Warwickshire Slogan (Different Design)

1st August 1957, Scout Jubilee Jamboree, Plain FDC, 2½d Stamp Only, World Scout Jubilee Jamboree Sutton Coldfield Warwickshire Slogan (Different Design). This version of the Slogan is Very Scarce Indeed. The only one I have seen. Was only used 1st July to 31st July 1957. So should not have been available on the 1st August (day of issue of the stamps). Good Clear Slogan. Cover in good condition for a commercial cover that has gone through the postal system.
