Well, I have been out-and-about gathering my evidence and started building categories. I took photo's of Graffiti and using GIMP I have created samples of some of the 'Tags'. Here's to a start.
This is the real photo of the Tag A. on a Canada Post Parcel Box.
And using GIMP, I took the photo and edited out everything but the Tag, and then cropped around. I have Tag A - E done and a right dozen or so more specimen's to catalouge over the next week just to build the foundation of the Tags around my house.This is the real photo of the Tag A. on a Canada Post Parcel Box.
