Between the dates 1860 -1874 there were three Royal Navy Fleet reviews, Aug 1865, July 1867,
and June 1873 all by Queen Victoria, this woolwork could well be a record of one of them,
Though sailors/marines were very competant at all kinds of crafts and hobbies whilst at sea, Scrimshaw work, modelling from bone and other "salvaged" material, rope and canvas shoes et al,
so it may be a gift for a family member when he returned home.
