Singers Garth Brooks and Leon Russell and the family of singer Bob Wills earlier donated items to the museum.
Blackburn still faces a challenge of getting lawmakers — especially Republican members in the GOP-controlled House who oppose any additional bond issues for state projects — to support a bond issue.
“On the Senate side … they've been saying they're willing to consider that,” Blackburn said. “We have not heard the same thing from the House.”
House Speaker T.W. Shannon, R-Lawton, said Monday he didn't know of any plans to revive a proposed bond issue.
“I haven't seen any specific legislation,” he said. “I'd be happy to take a look.”
Blackburn, whose agency would manage the museum, said it would produce about $2.1 million in annual revenues to pay for its operating costs.
Revenue would come from admissions, gift shop sales, special events and revenue from its 650-space parking garage.
