11 ‘F’ Pentominominoes by John Devost

I spotted this design on Ishino’s site early this year and decided to make a copy.  The designer is unknown and features one solution in the 4x4x4 box that I made for it.  It also features only one solution in a flat 8x8 configuration.

Both solutions contain voids making this a very tricky solve and I also made extra cubes that can be used in the solve but not really sure if that helps or hinders your progress? (See last photo)

Maple was used from an antique upright piano with Padauk Slipfeathers.

Contains a printed solutions sheet, signed and dated.

Shipping cost to be calculated at end of auction.
