Here are all the things I bought to do this:
Backing got this printed from vista print (A2 size)
I used Velcro sticky pads to stick the cover to the backing, I wouldn't recommend putting them on the vinyl if you ever want to play it again.
And lastly I used regular glue stick to stick the backing to the frame backing.
Also to note: when the the vinyl is in the frame it will stay in place without velcro and the backing will stay without glue, I just used these to guarantee it doesn't move.
I purchased the frame from Amazon and the poster was a present from a while back.

I purchased the frame from Amazon. As for the poster, it was a present so I'm not sure where it was from. Glad you like it!
