Abstract: The present invention provides for a poker game wherein the amount of successive wagers is pre-established. Each hand is preceded by players making at least one initial wager. A dealer also provides himself/herself with a plurality of cards and each player is displayed at least one card to form an initial partial hand. The players are given the opportunity to view their initial partial hands and are then required to increase their wagers by a predetermined amount in order to continue playing that hand. If the player increases his/her wager by the predetermined amount, then the player will be displayed at least one additional card. Various embodiments of the present invention require subsequent wagers in different amounts. For example, one embodiment requires a player to place two subsequent wagers in amounts equal to the player's initial wager in order to complete the hand. Alternative embodiments require players to make more than three subsequent wagers in equal amounts in order to complete the hand.

Abstract: A photographer's backdrop includes a spunbonded olefin material which is prepared according to several methods. According to one method of preparing the material, the material is softened by crushing it to break down the fibers in the material and render it more supple prior to the application of paint or dye. According to another method of preparing the material, acrylic paint, spray enamel, or soluble dye is applied to the material. After the material is completely dried, it is crushed (again) to assure a soft supple quality. Preferred aspects of the invention include: using a spunbonded olefin having the characteristics of DuPont TYVEK.RTM. #1422R which has one side which is relatively absorbent and another side which is non-absorbent, applying paint or dye to the relatively absorbent side of the TYVEK.RTM., and crushing the TYVEK.RTM. before and after painting or dyeing.
