I love these Marvel 3D-letter designs by Reagan Ray which he explained in a recent post:
I just started getting into comic books for the first time a few years ago. My son was interested as well, so we started making regular trips to the comic book store (pre-covid, of course). We loved looking at the artwork and lettering of the older comics. And like most lettering, right around the late 90s, it all went to shit. The hand-lettering masterpieces were abandoned for fonts and photoshop effects. With that said, I limited this post to the pre-’00s. I wanted to do something more vintage, but there are just too many from the 80s and 90s that I love. My absolute favorite was seeing all the interpretations of 3D type.
They’re all amazing and I’d wear each and every one of them on a t-shirt.
