Ok, I am just posting this to confirm with everybody, that I am going to BrickCon on Saturday! I will be wearing a black shirt that says "I AM MR. LEGO" with a picture of my buddy icon on it. I am short and I have brown hair, so be looking for me. Tell me if who is going so I can see if I can find you on Saturday...
About this creation
Also, I got this piece a few years back in a LEGO set, but it doesn't say LEGO on the studs, like it should, it also doesn't have the piece number! Isn't that weird :P This is a LEGO piece though!
I got a weird brick like that to in a set I forget what but it was a grey brick and it sayed TYCO on the top of the brick what do you think it means it did come in a lego set though and it doesn't have any thing on it that say lego like yours I don't think it has a brick number either but it's hard to tell.
About the LEGO piece, I have a 2x2 inverted slope where one of the LEGO embosings is rotated at a very peculiar angle. I also have a 2x2-2x2 Bracket that is a mixture between both light bluish gray and dark bluish gray. Think of it this way, you have an uber rare LEGO piece. The negative of this though is that you really have no proof it is LEGO and people will doubt. Also, I wish I lived in Washington right now and had a ticket that way I could go with you or meet you and hang out.
