Need Help Identifying What I Recieved.

I am new to Cel collecting so please forgive me if this is obvious to some. Recently I purchased a bunch of Vampire Hunter D cels and in the mix of them there were 4 sheets stabled together. They almost look like dougas or story boards. Two of them are hand drawn and the other 2 are photocopies (in sequence). I posted 3 of them on one page and if someone could look into my gallery and tell me what they are it would be greatly appreciated. The 2 that are in color are hand drawn.

Thank you!

They appear to be layout drawings.

I appreciate your help. Thank you!

I'm glad I could assist. Layouts are really cool- I have quite a few of them.

Good luck with your collection!
