Going by the state of his shirtsleeves and his hands, Daddy works at a job that involves lots dirt and grease, so much that it won't come off no matter how he scrubs. (Perhaps a mechanic; a welder; a machinist.)

[Daddy is a professional who's building the cottage he's in. - Dave]

With the unpainted block walls, shuttered windows and rustic furniture, I'm guessing this was a hunting fishing cabin.

Happy Easter fellow Shorpyites.

Could this be in dad's basement man cave? Cinder block walls with no paint. Stacks of wood/ moldings about the area. Pencil sharpener attached to the door jam. Definitely not the living room.

[wet_powder nailed it. It's the living room of a vacation cabin. - Dave]

Plus he's a two-ashtray man. When smoking was king.

Does anyone else think Dad looks a little like Howdy Doody?
