This is a Bohemian Czech art glass pitcher or jug with two tumblers, and signed or marked on the bottom of each piece. The maker is Kralik. The date is circa the 1930s.
You can view this pitcher in the book “Collectible Bohemian Glass 1915-1945 Vol II” by Robert and Deborah Truitt on page 61. The authors also say the maker of this pitcher is Kralik. The mark on the bottom is also one known to be used by Kralik.
On this page the authors write “Thin wafers of millifiori cane are picked up on a cylinder of hot glass, reheated, then mold-blown to produce the type of glassware shown on this page.”
Millefiori glass canes are fused bundles of glass threads, then cut across to show the pattern inside. This is a standard definition of the term.
The green glass glows under a black light. The outside of the green glass has a slightly oily feel, so it is possible that it is uranium glass, or Bohemian Vaseline glass. If you look to the book, you may be able to make the determination for yourself.
The pitcher is 8 ½” high and 6 ½” wide at the belly. The two tumblers are 5 ½” high and 3” wide at the mouth.
The rims of the tumblers are polished flat. The mouth rim of the pitcher is round. The handle of the pitcher is applied.
The green glass has a bright orange overlay of horizontal and vertical lines. There are horizontal bulges in the glass. Additionally the pitcher has four indentations around the belly.
The bottoms have a small indented circular pontil mark.
There are no chips, nicks or cracks except for a little bit of pinprick nibbling at the rims of the tumblers, very tiny and difficult to see and feel. There are some small air bubbles; one air bubble is at the rim of one tumbler and it gives the appearance of being a chip, but no, it is merely an air bubble and part of the glassmaking process.
The mark on each piece is Czechoslovakia in a half circle.
