Tribal Mask Fancy Cancel? Or Someone Having Fun With A Sharpie Marker?

Is this a known cancel or just a blob with shape?

Looks quite genuine.

has this listed as from Naperville, IL. There is a category "Masks" that made the search easy enough. Nice to get this on a Columbian!

While that reference covers the banknotes era, there were a lot of cancels listed that were used before the 1870-94 time period and a fair number used well after that. So it's worth checking it out for those. The 20th Century database hopes to list whatever was used 1894 to date; a few of these old ones were reused up until the 1930s, at least.

hy-brasil, thank you.

I'm a goofball. First site I checked was stampsmarter. I even searched by subject. When I clicked on the drop down arrow I didn't scroll down to the 'masks'.
