Japanese Bath Slippers

From Marina's WC testimony:

Mrs. OSWALD. These are Lee's shoes.
Mr. RANKIN. When you say the shoes, you pointed to Exhibit 149?
Mrs. OSWALD. Yes.
Mr. RANKIN. This is a pair of shoes of which Exhibit 149 is a photograph.
Mrs. OSWALD. These are his bath slippers.
Mr. RANKIN. Exhibit 148 are his bath slippers?
Mrs. OSWALD. Japanese bath slippers. These shoes I have never seen.
Mr. RANKIN. That is Exhibit 147, you say those are shoes you have never seen?

Could exhibit 148 be the yellow "slip-ons" described by Cliff Shasteen, the barber?

Mr. SHASTEEN... When he would come in, he was alway disgruntled, and the only time I ever saw him smile he had on a pair of yellow house shoes and I never saw any like them before.
Mr. JENNER. Sneakers?
Mr. SHASTEEN. Yes; slip-ons, only they were a little heavy--they were just a little heavier than just a common house shoe, and I admired them and I said, "Them looks expensive," and he said, "They are not."
"He said, "I gave a dollar and a half for them." I said, "My goodness, where did you get a pair of house shoes for a dollar and a half?" And he said, "Down in Old Mexico."

I do find it curious that the WC never asked Marina about those yellow "slip-ons" and pointedly fail to mention the color of the "Japanese bath slippers" identified by Marina.
