I hope that someone here can help me remember where I found this, because google is not proving helpful at all for me!
There was a site where you could pick a famous landmark (like Acropolis, Eiffel Tower etc), choose a date and time and it would do a composition of what the sky will look like (or looked like) on the chosen day and time. Then if I remember correctly you could buy a print of the picture.
The picture was somewhat realistic, not a planetary chart!
Sounds familiar to anybody? Can you please help?
