National Maritime Day in USA 22nd May

Days of celebration seem to come thick and fast at the moment and in the USA today is National Maritime Day when people remember those involved in the maritime trades.  I came across this fact while browsing on the internet researching for future work on my stamp collages, which often feature ships and boats.
My research recently took me to Bristol where I visited  the M Shed situated on the harbourside near the SS Great Britain, which I have yet to visit!   I found many interesting exhibits inside including a model of the Severn Trow Alma,  detailed in the Museum's label shown here.  A great subject for one of my collages, so must get sorting out the stamps!
