Caswell Galleries showcases hundreds of moldings for custom-framing projects as well as an extensive selection of prints that have been featured in hotels, restaurants, and other art-starved structures throughout New England. Professional frame affixers can mount and mat a family portrait or a photo snapped during travels abroad with typical projects costing about $150, though prices vary according to frame selections and how valuable a treasure map is hidden behind the image. Their collection of Boston and New England artwork illuminates the distinct sights and beautiful landscapes of the region with pieces by local artists such as S.C. Sabina’s Swanboats In The Garden ($100 for 18"x24" limited edition print), Jon Smith's Fanueil Hall, and Kevin Youkilis's First Base: Deconstructed. Caswell also boasts an abundance of vintage prints such as the popular Chat Noir poster ($120 for 16"x20" print matted and framed) alongside museum classics to infuse homes with an added sense of sophistication.
