These vases were brought over from Holland in 1912 when my Grandmother immigrated here. They belonged to her Mother and are from around 1890. I believe they are porcelain.The 2 handled vases stand 6.75" high and 4.5" at the widest part. They are both in good condition without chips or cracks. They are stamped on the bottom with numbers or letters but it is hard to decipher. Possibly 6024 and 6025. The oval bowl vase stands 4" high and about 5.5" wide. It has a crack on the right side as seen in the last 3 photos. It also has some numbers or letters stamped on the bottom.
