Three Late 19th C. Milton Bradley Froebel Kindergarten Gifts (Blocks) Boxes (Empty, As Found)

No blocks inside of these, but they're great slide lid, corner jointed boxes useful for all sorts of things, and of course as a lover of all things Froebel Kindergarten, and early Milton Bradley, I could never pass them by. One label for Gift 3 (eight one inch cubes), and one for Gift 4 (8 oblong blocks) and the third label partial, so not sure which. There is a fourth box too with the label almost entirely gone, which I'll send along too unless you tell me not too. Late 19th/very early 20th century.

Each box measures 2 7/8" x 2 3/4" x 2 1/2" t. As noted, there is a fourth as well (pictured in last two photos) which no longer has a label on it, but which I will send along as well.
