I got this stamping plate for my birthday in July, while it isn't strictly Halloween themed it has images from Tim Burton movies which tend to be darker and slightly horror / spooky themed.
The stamping plate is a different shape to any I own, rectangle but smaller than traditional rectangle, 6cm by 9cm. It has 21 images on it and all of the images I have used so far have stamped across really well.
Here are some designs I have done using this plate;
