Question: Is the cancellation (killer) made up of horizontal straight lines, and the postmark (town and date) inside a circle?
Like this?
Now, please be sure. The postmark must be a circle,
not an oval
or square box .
The cancellation must be horizontal lines, not lines at an angle
or flag-shaped
, or wavy lines
, or a printed slogan of some kind
Yes [postmark is in a circle and cancellation is straight horizontal lines]
No [not a circle with horizontal lines]
