"A Touch of Magic" https://archive.org/details/TouchofM1961
"A Touch of Magic" is the MPO produced, GM financed sequel to "Design for Dreaming." Nuvena herself , Thelma "Tad" Tadlock stars in it once again, and it is just as bonkers. 1961.

If anything, it's actually much, much stranger than Design For Dreaming. Think hilariously over the top pantomime and a "princess and knight" scene that doesn't have much to do with anything and has the production values of a kindergarten pageant. Nuff said.
