1974 Frankenstein APC Puzzle Glow In Dark + Box Universal Monster 1 Pc Missing

Beautiful puzzle from 1974, featuring Frankenstein, aka Boris Karloff. It is missing one piece, located right above his head. A complete puzzle such as this would be 307 pieces, but it is now 306. The pieces are in near Mint condition. Clean and crisp. One piece has a crease. As for glow, it only highlights certain areas and seems to be weak in its glow as it is 50 years old! As for the box, it is still holding up,no broken corners, and no sign of stress. May be some rub off here and there on the color. No marks or tears. There is clear tapes on the box, which i have not been able to remove because I misplaced my heat gun.
