The three variants of the postcard were printed before the concert. Each measures 4 1/2" x 7".
1st printing A postcard reveals a flying creature with the same color face and body.
1st printing B shows the creature's entire face is lighter than the body.
1st printing C shows the upper portion of the face matches the body and the bottom part of the face is lighter than the body.
There were also some pre-concert double-sized mailers printed that were conjoined with the BG088 image. There is some inconsistency in the color of the creature's face on the BG087 side of these cards. They measure 4 1/2" x 14".
