Why, thank you Professor and Miss Scarlett! Yet another sterling broadcast production, whimsical riddle, and high artistic value stationery and QSL. What an effort!

. Oh yes, I did appreciate the finishing gesture of the 1967 5-cent VoA stamp on the envelope, nice touch! Bravo!
👏(Note: Back of QSL and envelope same as an earlier BBPRN QSL/Langyard post)
