British advertisement for UK amplifier manufacturer Selmer, featuring two newer models: the Compact 50 RSV and Compact 30 SV. McGuiness Flint had had some chart success in the UK in late 1970/early 1971.
You're in on the big time when you chose Selmer amplification equipment. Fabulous sound. All the power you need. Enough to knock the roof off any concert stadium.
