That brings back memories! My grandparents had a Vornado in the utility room window that was a bit larger and had the fins on the back side for directing the air. Three speeds, on high it would pull air in from every window in the house. I think theirs pivoted from the sides to exhaust or pull outside air in - which I don't think they ever used. It stayed in the window for the entire spring & summer.
That is a very nice gift - now you won't need air conditioning this summer and you'll save a fortune on electric costs!
