After seeing peculiar signs in the posters archived in this thread, https://voat.co/v/pizzagate/1440615 I did a bit of digging on the two artists who make the posters.

Sophie McTear Design and MagickBat

Sophie McTear Design information is pretty easy to find.

Here is her website: http://sophiemctear.com/

I learned that Sophie is a young artist from the DC area

You will notice that there are only about ten posters on her site, so i checked her instagram link on her site. https://www.instagram.com/sophiemcteardesign/

I will admit that her posters do not seem all that weird with the exception of a couple.

This poster has a picture of childrens underwear on it. https://www.instagram.com/p/BC_vRLRgqrT/?taken-by=sophiemcteardesign

Many of her other posters are focused around an eye which seems to be a real them

In the press section of her site: http://sophiemctear.com/press

i found this story about Sophie and another local artist from DC, Jourdan Betette, being two featured artists at an art and music festival called Salta Bloss. http://thejoodlumgroup.com/whats-what/2015/3/24/salta-bloss-jourdan-sophie

MagickBat was tricky, though. http://www.magickbat.com/ takes you to squarespace but the site seems to be gone. I checked the wayback machine, and found all of the artists posters. I cannot find a new domain for MagickBat's work, it just seems that the artist doesnt have a site. https://web-beta.archive.org/web/20141219123753/http://jourdan-betette-f1zr.squarespace.com:80/show-poster-test/

Now, these posters are a little bit more bothersome. some include pentagrams, upside-down crosses, eyes, and other weird images.

When i google magickbat, i found an online vender at two stores, one at depop, and the other at Society6. Society6 is a large platform for selling prints of art. Depop is a social shopping app that you can sell your own belongings on to friends and followers. I also found a facebook page for MagickBat.

Her facebook page states she is a local DC artist, as well. By checking her profile picture here i have also confirmed the online vender to be the same person.

So, if you havent noticed yet, MagickBat is Jourdan Betette.

Her depop page is important because these items appear to be items she owned herself at one point.

-A shirt that says, "Satan is waitin' " - SOLD

-A phone case that says, "Gypsy Warrior" with many occultish symbols

-This top that is said to have kill star symbols and is tagged as #occult #pagan: https://www.depop.com/magickbat/kill-star-symbols-too-size

-"death metal dolly" if you view both pictures of the shirt you will see on the back there are three 6's, three upside-down crosses, and a pentagram

So we have this person who wears satanic clothes, drawing satanic images, for a questionable pizza parlor, that hosts questionable bands containing pedophilic imagery, and content.
