Two pieces on the top shelf are not crackle. The cruet on the left is ribbon glass and the one on the right is millefiori (thousand flowers). They both date to the 1890's.
The three pieces below are sort of unique. The salt and pepper shaker are collectible in two categories, crackle and as a salt and pepper set. If you look closely at the middle shelf above you will pick out a small blue salt and pepper set. The middle piece is very collectible because the stopper is still with the piece. Apparently stoppers are easily broken. The third piece is collectible because of the height and shape of the piece.
A closer view of the millefiori and two crackle pieces.
The keen observer will have noticed the toy Harley Davidson motorcycle with sidecar. I also collected toys and have several hundred transportation oriented toys. It is a eclectic collection of whatever caught my eye.
