This puffy heart with fabulous repousse design of Little Boy Blue blowing his horn while sitting on a wood fence in a detailed grass field is actually a rattle made by Adie Lovekin, known for their silver items in the late 1800's to the early 1900's, including sought after pin cushions and rattles. The smallest heart rattle that I could find that Adie Lovekin made measures 1 1/2" in both dimensions. This one measures 3/4" long and 3/4" wide, making it a perfect charm size. The only difference is that it has the little openings at the bottom to allow the rattle sound to escape. Except for the little holes at the bottom, the heart is sealed along its sides. There are two little holes but one has become slightly enlarged. I would think that the larger hole could be adjusted to match the other one quite easily. I have shown the enlarged hole in detail to show it is not bad at all. I thought it had lost its internal rattle beebees, but in fact they or it is present, although it gets stuck and only loosens rarely or when shaken vigorously. I believe it is slightly short of perfect in its shape with small amounts of imperfection. The bail is a little curlicue shape. It must have attached to something but I do not know what, not being a collector of rattles. Some and most, I believe, of the larger hearts were attached to teething rings, but this one is too narrow to attach to something that a baby could use to teethe on. Perhaps, for the rattle collector, the original attaching piece could be found and it could function as intended for a collection. Both sides are the same but one side has hallmarks. There is the makers mark of the Adie Lovekin Company (ALL) and full hallmarks for sterling, Chester, and 1920. I believe this is a rare size as well as item, and it is very imposing with its beautiful detail. The heart weighs 2.2 grams.
