“Is there anything else that stands out as potentially fake here?”
Yes.
1. The neither the outside nor inside envelopes have been sealed.
2. Pennsylvania is one of seven states that does not allow election workers to begin processing absentee or mail ballots until 7 a.m. on Election Day. (https://www.msn.com/en-us/news/politics/elections-101-why-precanvassing-rules-for-pa-mail-ballots-frustrate-voting-officials/ar-AA1sFtxe)
2. Because a state "does not allow" election workers to begin processing ballots until 7 a.m. on Election Day ... that is a guarantee that no ballots will be tampered with prior?
Come on now.
In all seriousness, if this is a fake, it's for some other yet unidentified (here, anyway) reason.
