Usually, I put the titles of the artworks in the title for the blog post, but considering the titles for these are kind of long, I decided to just use the title "Superman Logos". The first one is titled "Supermen - The Blur Logo". That's the one above. I basically took a picture of the Superman logo and photoshopped it to look like the logo on the shirt part of Clark Kent's "The Blur" costume on Smallville. Someone asked if I could do a logo like that for the villain Zod, so I did it. There it is below.
It's titled "Superman - Smallville Zod logo". Like with The Blur logo I photoshopped a picture of the Zod logo to look like the logo on Clark Kent's shirt part of his costume does.
