Stewarts of Scotland

I belong to the Stewart clan and am related to the Stewarts of Bute though I have never met any of them. 
Saw this in the local charity shop and thought one of the girls might like it (though probably  not)
When I got it home, I saw there was some information on the back so I googled it. Laurie's of Renfield St started off making bowling balls then diversified into selling tartans, kilts etc for the foreign market in the 1960s. They were also ahead of the curve regarding sustainability as it says " this plaque  started life over 150 years ago when it was planted as an oak seedling in Scotland.  So an interesting wee plaque  and a good wee historical  find.
