Can anyone help me identify the font used for the heading of the following poster?
It looks like Impact font to me judging by the long letters and somewhat condensed shapes. All they did was used a bevel or inside shadow effect and applied a warp or a text shape to the word. Check this link out and use show by its caps. http://new.myfonts.com/fonts/urw/impact/%7CImpact
Here's my quick rendition -- you can tell those letters match distinctively.
We get a lot of font identification questions, you should check out this link.
However, I ran the header through WhatTheFont and some close matches were:
Though, the R doesn't have the curve on the bottom...
Though, the font isn't as heavy...
I hope this helps.
As for the "retro" effect, I would duplicate the font layer, and change it to black, and drag it down a little bit (creating this sharp shadow). Then, I would use the pen tool to create those lines you see on top of the letters. It also looks like all the letters have a stroke around them, so I would add a black stroke too.
This technique should be nearly identical in both photoshop and GIMP.
EDIT Mike's post includes the correct font, which is Impact.
