We’ve got another optical illusion on deck! This Official Postcrossing card comes from Germany! I think it’s a little easier to see what this is supposed to be now that I’ve scanned it… but it honestly took me about 20 minutes to realize what it was! The shading is much fainter on the physical card, so I was turning it, turning my face, moving it further away, putting it under a microscope, etc. trying to figure out what it was! But I think what eluded me more was the text in the upper-left corner actually stating what it was. My eyes are usually pretty reputable, but this time was a miss. It’s okay, my fellow “pupils”! Regardless – I LOVE this postcard! Thank you so much for sharing this with me and for all your kindness, Desch!
