We wanted to show you how we framed this amazing vintage “Berliner Weisse” Beer cardboard advertising. Because it is slightly three dimensional we wanted to give it some space in the frame and sink floated the piece in a double mat with nice wide margins. The collectible is attached with archival hinges, so there is no glue touching the cardboard. The rest is standard museum quality framing: no acid, uv filtering acrylic glazing, a nice backing paper for dust protection and a beautiful walnut hardwood frame from Picture Woods in Colorado. Another amazing piece of art framed right here in your San Francisco neighborhood frame shop.
