yea, a bit redundant, but I'll give you two guesses where LogoType got them from.

You almost had it but said it backwards.
I created a lot of this stuff when I was dig into the vinyl cutting and sign making scene. Started a business and decided the return was too small for the effort.
Left to it's current layout adding the logos and repro stuff would get out of hand, but once I get the menu system down for it, browsing and finding what you're after should be easier.
I'm looking at it this way, acceptable company logo's would be those for the arcade industry (used to make repro artwork for restorations) or those related to the games themselves, ie Star Trek, Star Wars (just don't tell George), etc.
I have no desire to duplicate LogoTypes site or the (recently closed

)beltonsigns site, but I don't mind being a "one stop shop" for related items. I know that for myself, I hate having to jump from site to site to find bits and pieces when I need something.
If it gets too big or out of control, I'll deal with it when or if it happens.
