Captain Upton's House (1927) is an oil painting by one of my favourite painters: Edward Hopper (1882-1967). And a sort of dream house. The sender of the postcard grew in a similar one. Alas, without the lighthouse. He wonders what looks it like today.
I wonder who Captain Upton's was. (See Bryon's comment!)
On the back of the postcard, very nice stamps with homes of all types:
