Not destroyed, but a pretty nice 1933 Goudey Clyde Manion and 1934 Goudey John Stone were creased by my mother in the mid-1980's. She got so mad at my brother Rhys for spending all of his money on baseball cards that she grabbed the cards, squeezed hard, and then threatened to throw them out of the drivers seat of the car (while we were moving). We pleaded with her to forgive the trespass and eventually she relented but forever those two cards were destroyed by my mother grabbing them.
