Not so quick Jzoook6,
 
	You have two totally different marbles here by two different makers. 
	If there is an Alley it would be the first one imho. 
	There is no “brick” here—just some very fine looking purple based/swirled marbles which are rare enough on their own.  
	Purple is a rare color in a vintage marble only outdone rarity wise by pink. 
	This is my opinion and I appreciate them all ---opinions ---regardless. 
	Marble—On!!
