Chicken Tracksby David Maresco
Here are two examples of what have been called chicken
tracks, for obvious reasons. Trying to determine which precancel overprint
it is and how many there are is a difficult task with these, but after
careful measurement, viewing with a X10 magnifying glass and comparison
with examples of single impressions of types K, L, M and N, I have
taken my best guess.Many of the early bar types can be difficult to identify
especially if they are light impressions.
