<p>In this case (and in many like it), the object pronoun “me” is both sufficient and correct. However, while most usage manuals will discourage the use of the reflexive pronoun “myself” in place of the personal pronouns “I” (subject) or “me” object, there is historical precedent for these usages. They are not incorrect, but they are much less favored.</p>
<p><a href=“Google Ngram Viewer”>Google Ngram Viewer; (Google Ngrams graph of “made by me” vs “made by myself”; note that to really be useful this should only graph instances of “made by myself” where “I” does not appear earlier in the sentence, but it does not.)</p>
<p>To my ear, the use of the reflexive in this particular example reads as a deliberate invocation of a more literary-sounding voice. It is not so much a case of “failing to sound more educated”, but one of “trying to sound more refined”. </p>
<p>I will grant you that depending on the expectations of the audience, the mere act of trying could be construed as a failure. The writer here is not wrong, but he is potentially out of tune.</p>
