I believe that this was during the time Binney and Smith, yes, the makers of Crayola, owned Hallmark and Monogram! There where a few other cars in the series and I remember my then girlfriend getting excited and trying to buy me the Monogram '56 Chevy! Good thing I was there to prevent this tragedy!!
They pop up once in a while at kit shows and I am tempted to try and collect them, but, I have no real idea how many kits where made in this series.
