I found the 22 story 1921 Cunard building 25 Broadway in NYC has a number of interesting nautical related keystones and carvings as well as ceilings since it was occupied by the Cunard ship owners. It’s interior is stunningly and it’s a designated landmark. The keystones and decorations include a figure blowing wind, snails and shells, but one thing that caught my eye was this roundel of a sailing ship, and it’s difficult to tell but the lower floors where this is located are carved stone, hard to imagine the detail on this being carved in stone which is why I think it may be terracotta with a matt granite glaze.
Of curiosity is the object the figure is holding in his hands off the side of the ship, it sort of looked at first like an oar but it’s not that shape, it also resembles a rudder but it’s not in the right location for one, maybe someone who knows ships can identify what it is.
A fellow on a sailing ship site says:
Its a Medieval Merchant ship with a ‘Steer Oar/Board’ which gave its name to the side of the ship it was hung(Right). Hence ‘STARBOARD’ side in order not to damage it along side,it would tie up on the other side ,Hence ‘PORT’ side(Left)
The three lions on the flag is the heraldic symbol of the Plantagenets in the United Kingdom.
