Lego 77906 DC Comics Wonder Woman is up for pre-order at Lego.com and Walmart.com.
This set says “Special Limited Edition” on the box and is very similar to the SDCC 2015 Lego Superman from Action Comics No. 1 scene.
The Wonder Woman set features Wonder Woman, Cheetah and Etta Candy. It has 255 pieces.
Since San Diego Comic Con 2020 was cancelled due to COVID-19, this seems to be the set that was meant to be exclusive to SDCC 2020 this year.
