Hulk & Children book cover prelim - John Romita

Hulk and a few children prelim or sketch done by John Romita Sr. Prelim is for a possible children's book, but I can't find anything with this particular lay-out on it. Don't know for sure, but it looks a bit like the Hulk and child that was done for the back of one of the Marvel Treasury Christmas editions. Not completely sure that's what it was for, but it's the closest I've found. It may just be a sketch done by John. If you know... please let me know!
