This postcard was given to me from an ex-girlfriend (non-affectionately known as “Crazy-nut”). This postcard was the best thing to come of our relationship.
Not only is it great for Love Your Pet Day, but this card is an excellent specimen of the gimmick class of postcards. As Pat indicates if you squeeze the card it does indeed squeak like a kitten.
“Squeeze and they’ll meow get-well wishes for you!”
In my years of collecting, I haven’t come across another squeaking postcard (the post office would probably think it is some sort of terrorist device). But I’m most surprised that they had such gimmicks back in 1964 (or earlier) when this card was sent.
