First let me see if my local blue printing co can do a drawing that is this large, 34" x 54". Or I can take a photo. Let me check.

Rex,
A 34" x 54" print/poster/photo can be scanned by a Blueprint Shop. Most print shops that cater to architects and engineering firms can scan large format documents. The output file can be in .dwg format; or .jpeg; or one of the other photo formats. If the operator is "knowledgable" they should also be able to "raster scan" at high resolution. A regular "photo copy" shop, is probably unable to copy that size print, unless in sections. But again, you would need to check. A "one piece" roll scan should keep all dimensions correct and to scale, an advantage over a multi-part pieced together scan.
For the information of other readers, U.S. engineering and architectural print sheet sizes, in inches, are:
A: 8.5 x 11
B: 11 x 17
C: 17 x 22
D: 22 x 34
E: 34 x 44
E roll 34 x ? ?
Further, there are any number of 'roll' formats where the length is virtually unlimited. Typical roll widths are 34" and 44". 48" and 54" are also available, but not as common.
Hope this is of some help.
