Brass Art Deco Box with stamp on bottom

I have found a small brass box with an art deco-style design etched on the top. The etching is filled with white. The inside of the box is lined with a red velvet material. On the bottom of the box is a stamped script signature, but it's not quite readable. It looks like L____ Sp_____ with both the first and last name ending in a 'tall' letter like a d or l. I would like to find out anything I can about who this maker might be, when the item may have been produced, and what it's original use was since I would not think a pillbox would be padded.

I appreciate any information or leads. Thanks!

Good
