As far as I'm fond of strolling about fleemarkets I will post now once in a while some acquistions here to let you know what I have seen or what I have even bought. In this case I bought it for 50 € cents. Not mail art but it could have been sent as mail art, to see whether it will arrive safe or broken into pieces.
Starting with this glas bowl, 19 cm in diameter, found at the todays fleemarket in Bad Kissingen; a typical american souvenir from the late 1960ies (I would say) the Empire State Building is still mentioned to be the tallest building in the world - it is made by Houze Art, PT. Marion PA, USA.
What do you think, trash or treasure?
