Summary Good

Assessor Samanta Pugh

Notes Top and bottom metal have some rust. Some black residue is present on the top's edge. Words on the top cannot be clearly read because of marks of a darker color all throughout the top. Bottom metal has some black marks/spots. The paper label is in good condition overall. There are some water stains all around the bottom edge. No tears are seen on the paper, only on the upper edge some superficial scratching reveals white color underneath the green. There are some minor dirt smudges on the label, but color and writing are quite clear.
