This is a humorous painting with a Summer Holidays kind of vibe.
I was thinking about how people used to abduct garden gnomes from peoples gardens and then send them photos of the gnomes in exotic often overseas locations.
I think the gnome in this painting has decided to take a holiday by the beach and has adopted a summery outfit - Sunglasses, Hawaiian Shirt, Cargo Pants and Sandals and has just bought an Ice Cream Cone Perhaps he feels a bit hot and bothered and is wondering if the beach is really not his thing ........
