I recently inherited both of these--I have fond memories of working the "On The Farm" one many, many times with my grandmother. Strangely, that puzzle is undated, and appears to be from the late 1960's, but more likely, the very early 1970's. The artwork is much older, and there are frame-tray versions of it on Ebay from the 50's.
The second one is called "A Jungle Snap," and is dated 1962. Both, luckily, are complete!
