Info 218: webfinds 1978 farm boy + girl

Anybody got these bigger sized? Not movie related. After searching for possible title and source for the unknown actress asked in the latest comment (also asked on the Overalls Forum and not even the uploader Tabman remembers the title and I also don't know it), I found 3 tiny pics on the Google cache. Type this search string on a Google image search

"Blueford" "1913 International Haverster"

Only few results as Bluford, IL and Harvester isn't spelled correctly.

Pic showing 8yo Rob and his sister Penny from Kentucky. Original forum post and description (but pics aren't available anymore)
