There are two varieties on this card.

The original card (on the left) was a much lighter printing than on the reprint. The "Egg" was nearly complete, but construction is still showing on the roof.

The cards are 4" x 6". The publisher was Plastichrome® by Colourpicture. Dist. by Avis Post Card Co. The card number shown on both cards is P311396. My code number 519 is shown in the lower left corner. Photo courtesy N.Y.S.O.G.S.
