Postcards with the best Hubble images • Personal and eye catching The front of the cards has beautiful full color photographs with some of the best Hubble images. The back of the card has a short faint description of the image depicted on the front of the card. There is, course, plenty of writing space for those who wish to send this lovely card to friends or family. The postcards are made using a high quality four colour offset process on a heavy 300 /m2 matte carton with a glossy front. Actual size is 17 x 12.0 cm. Please note that the representation here on the web does not do the real postcards justice.
