HF Pottery, a.k.a. House of Favors Production years: circa 1940 - 1993 HF provided mugs for Steve Crane Associates (Beverly Hills Luau, Kon-Tiki chain) and the Mauna Loa in Detroit. The HF refers to 'House of Favors' from Boston which wasn't a pottery company but a restaurant supply company. House of Favors outsourced items and put their own label on them. Favor-It Brand was the trade name for the HF importing business. The origin of mugs with the HF label is still uncertain.
