Walther-Glas flower fancies cake dish

Charming rectangular dish, cake or canapé plate in glass, partly coloured, with raised floral patterns underneath (the top part is smooth). This is a dish from the famous German brand Walther-Glas, a company that was established in 1856 and closed its doors permanently in 2013. Often, this brand is referred to as crystal, but here no information on the box allows me to confirm that; however, in any case, it is a very high-quality glass with beautiful transparency. This dish is part of the "flower fancies" collection. It probably dates from the late 90s. It is in perfect condition, with no chips or scratches, and has likely never been used. It is still in its original box (the box is a bit worn). It measures 39 cm in length, 18 cm in width, and 4 cm in thickness.
