vintage milk glass coffee mugs, letter T monogram initial in chalkboard black

Set of six vintage milk glass mugs (heat proof Federal glass) with the letter T in a matte black finish something like chalkboard paint. The paint is a original to these mugs, slightly worn, not a new paint job.

The mugs are clean and in good condition without chips, cracks or staining. They're 4" tall, nice tea mugs or coffee mugs.
