Vintage Akro Agate orange and yellow slag glass child's octagonal tumbler cup. Measures 2" tall. Maker's mark embossed on bottom. In very good condition with no cracks or scratches. Tiny chip on base (see last photo) and some slight roughness around rim as you run your thumb over it. Not enough to even call a fleabite. There is an orange stripe that runs the length of the cup inside and out. It looks like a hairline crack but is actually part of the slag pattern.
