The Public Domain Mark (PDM) is not a copyright license, but a symbol used to indicate that a work is in the public domain. When it is applied by the author or the copyright holder, community consensus has decided such works as being public domain in the US and countries where it is legally possible to release own work to the public domain. In the countries where this is not possible, the copyright status of the work remains undetermined.
If a file is tagged with Public Domain Mark by someone other than the author or the copyright holder, a more specific copyright tag such as one found at Commons:Copyright tags/General public domain must be applied. If this is your own work, please use {{Cc-zero}} instead.
This reproduction is permitted under the Article 45 of the Salvadoran copyright law, which states:
the following shall be allowed without the consent of the author or remuneration: . . . the reproduction of a work of art on permanent display in a street, square or other public place in an artistic medium different from that used for the making of the original; with regard to buildings, this right shall be limited to the outer walls
