Outstanding collection of early 1900's boxing cabinet photos from local Pittsburgh fighters Al Grayber and Leo Houck, some signed.  Collection includes Young Jack Redmond 6x9", Leo Houck (signed) 6x8", Young Britt (Henry Treffinger) 6x8", Jack O'Brien 6x8", Monte Attell 7x9.5", Red Robinson 6x9" (signed by Manager J.R. Mason), Earl Denning 6x9" (possibly signed), Jack Houghesty 6x8" (possibly signed) and Ken Rock.  Nice collection.
