Purchased from the Netherlands in the middle of the 20th century old antique key ring early oil lamp shape only black

Purchased from the Netherlands in the middle of the 20th century old antique key ring early oil lamp shape only black After the Second World War, Europe was fully revived. The key rings of that period were mostly for publicity purposes. Manufacturers were also related to people's livelihood products, whether it was food, cleaning supplies, cigarettes, toilet paper, packaged food, etc. The rest have fairy tale or story content. French fries and Mina's key ring are old-fashioned features, and there are no manufacturers to produce such key ring clasps. Please refer to the photo for details. If you are very strict with the new and old details of the product, please consider carefully and purchase again. Thank you.
