Expertic Collectibles
"Expertic" is one of the keywords we use to seach on Ebay for collectible items exported from East Germany during the DDR times. I believe the items with this sticker were exported for their hard currency value.
"Expertic" is not a commonoly appreciated word so a search for this term sometimes finds items that are overlooked by other shoppers.
We like to collect older German collectibles, especially ones that are not really expensive. We also focus our collections efforts on DDR Zeit related collectibles and older items from the Erzgebirge region of Germany.
We are gradually building up a nice collection. If you see items listed with a "Buy Now" button it means the item is for sale.
