Vintage HTF Green Christmas Holly Berry 4 Piece Mug Set

Vintage 4 piece Christmas mug set -Green mugs with lighter green holly leaves & red berries Some very small white areas on the lighter green- maybe where they missed getting painted or glazed?? (please see all pictures) One mug does have a small chip/nick on the back(shown in the picture) Very pretty displayed! These have a business card & small Christmas greeting paper insinuating to me that they were probably given out by Sunderland Bros. in Omaha, NE as a Christmas gift/promotion. Will include with the mugs. Experienced shipper- will package with care.
