🔎 UNIDENTIFIED Any possible ID?

Anyone know what this could be? Looks to be some letters scratched in on the outer rim, it's the shape of the umbrella the girl is holding. Found some markings on the back but can't quite make out what it says, there looks to be a logo above the marking too. Found at an 1890s site. Thank you
