Have also seen similar ship paintings, very often on walls of doctor's offices. A popular subject and no doubt favorites get often imitated be it by hobbyists, art students or AI generators. I wonder who thought of it first? Probably not some guy in a landlocked cave, that's for sure. 

Love the little girl in the field with her kitty! Kids, cats and flower gardens are also very popular subjects, maybe because there's so many of them about if one is in the mood to paint. My grandparents and greats had similar pictures in big old Victorian styled frames on their parlour walls. Not proper paintings of course because (a) not many artists around this town back then and (b) way too poor for things like that. Just very nice prints that in most cases used to be calendars.

Yes, definitely Sherlock and Mycroft. 

Gah! Just noticed the borked right hand.
