This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason:

Public domainPublic domainfalsefalse

	Autor suri 28. september 1936. aastal, seega kuulub see teos avalikku omandisse päritoluriigis ja teistes riikides, kus autoriõigus kehtib 70 aastat pärast autori surma või vähem. See fail on Ühendriikides avalikus omandis, sest see avaldati (või registreeriti USA autoriõiguse ametis) enne 1. jaanuari 1929.
Seda faili peetakse autoriõigusseadusest ning kõigist seonduvatest ja ligidastest õigustest tulenevalt teadaolevatest piirangutest vabaks.

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.
