Huh, never thought of trying to get the entire puzzle slabbed together.
I'm S L O W L Y trying to build the basic 1935 Goudey basic set while assembling a few puzzles. I've chosen to keep it raw because it's easier to put the puzzles together. The few I've purchased that were graded I have cracked out.
However, some of the puzzles (puzzle 1, 8, and 9) are comprised of 12 cards...not sure if they make slabs big enough.
I think 1935 Goudey is a set best collected raw. Here my two completed puzzles so far:
