Rome Album Cover Inspiration?

Rome is a great album recently released by Dangermouse and Daniele Lupi, featuring the likes of Jack White and Norah Jones. Yesterday, I came across a stamp from the Netherlands dated 1970. I knew instantly, that I had seen  it somewhere before, see what you think!

The designer of the Rome cover is Jacob Escobedo from Nevada. He grew up surrounded by his father's collection of oddities. He has some great work on his site: http://jacobescobedo.com
