IS ALL SIGNED ARTWORK LIMITED EDITIONS?
Not necessarily, some artist sign their art to give a more personal or valuable appearance. Right or wrong if the image is not numbered it is still an open edition piece that may happen to have a signature on it. The exception to this is if it is the one and only or it is the original piece that a numbered edition is reproduced from. Then, there would not be an edition number. Some artist may put 1/1 on the art to indicate that it is the original piece. Another example is an artist may sign a piece of artwork at a gallery reception. This could be an open edition piece that was intended to simply be an announcement of the artists show. Depending on the artist, a piece like this could actually end up being valuable some day.
