The Mamas and Papas had six top-5 hits in 1966 and 1967 including “California Dreamin” and “Monday Monday.” Their 1966 album “If You Can Believe Your Eyes and Ears,” released by Dunhill Records, is worth up to $30.00 if the cover view of the toilet is blocked as seen on the right. But if there is a full view of the toilet, as shown on the left, then the value jumps up to $250.00.
